Putter Fitting: Why everyone can benefit from Quintic
This is the first installment of a four-part series from Modern Golf on putter fitting and Quintic System.
When it comes to putting, everyone thinks they’re an expert.
At least once, we have all been told what we were doing wrong on the putting green and how we SHOULD fix it. We see this universally — most golfers want to help other golfers get better. But are they really helping, and is the information they’re sharing accurate?
The truth is, without quantifying the given information, the answer is usually no. A system we use at Modern Golf called Quintic Ball Roll provides these answers by accurately measuring the interaction between the clubhead and ball. By doing so, a golfer can identify why they have certain habits. More importantly, they’ll know how to make the proper changes. Tangible results are the key to helping golfers with their putting technique and thus, the study of ball dynamics is here to stay.

The Quintic Ball Roll portable unit consists of software and a high-speed camera that can be connected to any computer. Quintic captures 14 different data points at up to 360 frames per second from the beginning of the stroke to the first 16 inches of the putt. What makes Quintic most useful is that it gives ball data as well as clubhead data graphically and numerically. This allows the golfers and fitters to identify how the head of the putter moves through impact and how this affects the roll of the ball. Making changes to the stroke and the putter becomes easier as information is quantified.
Golfers of all skill levels can benefit from using Quintic. For a novice golfer, identifying something very basic in their putting stroke can have a measurable impact on lowering their scores. Something as simple as controlling launch angle can take strokes off ones game.
Some of the best players in the world are also using Quintic on a daily basis. Quintic has helped Rory McIlroy, the world’s No. 1-ranked golfer, as well as FedEx Cup Champion Henrik Stenson and Open Championship winner Darren Clarke, to name a few. For these players, making or missing a putt can be the difference between winning and losing, and hundreds of thousands of dollars in prize money.
At Modern Golf, Quintic plays an integral role in our fitting experience. It eliminates any guess work involved in selecting a putter or fitting a player’s current putter. Through the collection of Quintic data, a professional fitter can then accurately and scientifically start to adjust an existing putter OR fit golfers into a putter that’s more suitable for their stroke.
Golfers can also instantly see why they may have certain tendencies. For example, if they have an inclination to miss putts on the left side from inside 10 feet, they may have a face angle issue. To make putts from inside 8 feet, we’ve learned that the face angle needs to be less than a 1 degree open or closed to the target. By identifying the face angle error we can help golfers eliminate that miss. In addition, all the data is saved for future reference to measure improvement.
Statistically, the greater mass of golfers are not getting any better at golf. How can this be with all the advances in knowledge and technology? We think it’s the inability of golfers to see tangible results. Taking a final exam and not wanting to know your grade wouldn’t make much sense if your goal was to get smarter. Players can see results faster if they can identify their flaws and then work to remedy those flaws. Turning three putts into two, two putts into one — that is how to lower your scores. Quintic gives golfers this real and reliable data. That why if you are not using Quintic, you are instantly at a disadvantage.
Sadly, most golfers who haven’t used Quintic are, more than likely, practicing the wrong technique. A golfer’s perception of what they think they are doing versus what they are actually doing is often skewed. So the solution is simple — no more guess work. No more relying on what Mr. Smith told you on the putting green just before you teed off on day one of your Club Championship. Whether you are a scratch golfer or 30-handicap, we guarantee results using Quintic Ball Roll.
During a one-hour putter fitting (it costs $100), our professional fitters will accurately adjust a golfer’s existing putter or fit them into a putter that is more suitable for their stroke and ball roll. Players will leave with a fully fit putter and data for their future reference.

AVL: We’re talking about practice! My best tips for taking your game to the course
With the beginning of June on the horizon and courses rounding into peak condition for the season, it’s time to hone the finer skills that often get rusty over the winter. More sunlight also means more time to get out on the course and work on your game.
Whether it’s the practice green or the driving range, there’s always something to improve—whether you’re enjoying the fresh air or preparing for a weekend game or tournament. You can work on drills or freestyle around the green, and friendly competition is a great way to sharpen your skills.
While there are endless ways to get better at golf, I’m going to focus on practicing around the green. Let’s take a look at a few things to keep in mind as we head into the summer months.
Drills
From the driving range to the practice green, it’s important to incorporate drills into your routine. Years ago, I spent a weekend working on my short game with James Sieckmann. He recommended doing drill work for 5–10 minutes, then returning to your main practice.
This way, you create a balance between structured drills and real-world scenarios, so you’re not confined to “perfect” situations. For example, hitting the same three-foot putt over and over is good for repetition, but after a while, it becomes less interactive for your brain.
My approach is to use a putting trainer with a narrow gate for the ball to pass through, or simply place tees just outside the width of the ball. I’ll hit a series of four putts through the gate for three sets. Then, from a similar distance, I’ll hit four putts without the training aid and repeat that sequence three times.
Next, I’ll hit a number of 15–25 foot putts in a random fashion, then circle back to repeat the short putt drills with and without the training aid.
This breaks up the rhythm of hitting short putts with the training aid. When you hit the same short putts over and over, it’s easy to get into a groove—which is great for the drill, but not reflective of actual course play. While finding a rhythm is fundamental for drills, I like to introduce variation with longer putts to keep things realistic.
Game Mode
Once you’ve established a foundation with drills, it’s time to simulate on-course scenarios. This is where a few practice games come in handy.
One that I’ve been enjoying lately involves putting 10- to 15-footers with two balls. If I make the putt, great! If I miss, I pull the missed ball back a putter length. Suddenly, that little tap-in becomes a nerve-wracking three-footer—at least at first. As you get better at this game, those three- and five-footers become much more comfortable and routine.
It may sound cliché, but each shot is just what it is—it’s how we react that makes the difference. I like this game because it blends the pressure of on-course putting with the consequence of leaving yourself a much longer putt than usual.
Another game I like is one I recently learned from Brad Faxon. Place three tees in a line at four different locations around the hole: one at 3 feet, one at 6 feet, and one at 8 feet. The 3- and 6-foot putts count as par, and the 8-footer is for birdie.
This game keeps you focused on scoring and helps you get into a competitive mindset. You can even think about this putting game while you’re on the course. I just started playing it, and last week I couldn’t get better than two under par.
Competition
Competition during practice is when drills and games come to life, and you start to see results. For me, nothing beats a putting contest with a friend or two. In the right setting, these contests can become talking points for the whole season.
Match play, a game of 21, or simply seeing who can make the most one-putts (with a small prize on the line) are all great ways to simulate real on-course pressure. Recently, I played in a putting contest where one competitor made back-to-back 30- and 50-foot putts. As they say, expect your opponent to make every putt—and he nearly did. That’s impressive, and it’s something you see on the course, too: you have to stay committed to your game plan, no matter what.
When it comes to practice, it’s important to blend feedback from recent rounds with the fundamentals you want to reinforce. Drills, games, and competition—from the driving range to the putting green—form the backbone of skills you’ll rely on during actual rounds.
Finding the right balance is something we’re all working on, one practice session at a time.

Seoul Sensibilities: Is Korean golf fashion starting to shape the world?
For Korean golfers, we always look forward to the last of the kkot-saem-chu-I for the true start of a new golf season. The term refers to a cold snap, but literally translates as “winter being jealous of the flowers beginning to bloom, thus lashing out one final time before surrendering to spring”.
A rather poetic mouthful packed into a short expression.
Koreans can be like that. Understated, yet oddly expressive at the same time. And nowhere is this more true on the golf course and in our golf bags. In fact, I suspect many Korean golfers look forward to new apparel and accessory drops more than they do actual equipment launches each year.

At this point, Korean golf fashion may exist on its own timeline. (courtesy of @seonbi_golfer)
There is ample evidence to support that suspicion. Korea is the world’s third-largest golf market behind the United States and Japan, yet its appetite for golf apparel exceeds that of both countries combined. Recent estimates suggest that Korea accounts for nearly 40 percent of the global golf apparel market, placing it among the world’s most influential golf fashion markets and punching well above its size.
Simply, we care deeply about how new golf clubs look and feel, but enjoy looking good while swinging them even more.
Golfers in the West may laugh and say that golf is played on a course, not a fashion runway. Perhaps. But what’s the harm in trying to look and feel good, if the added self-confidence can help actual performance? It certainly seems to have worked for Jason Day, who may have unlocked a new stats category: dormant strokes gained. Coincidence?

During the COVID-era, estimates placed the market near $9 billion, an astonishing figure for a single country.
As a proud member of Gen X, I’ve witnessed the highs and lows of golf fashion firsthand. The pleated trousers and wing-tipped shoes of Jack Nicklaus, the stylish plus-fours and knickers of Payne Stewart, the baggy black trousers and fitted mock-necks of Tiger Woods, and the thigh-hugging athletic tailoring of Rory McIlroy. Golf fashion, like the golf swing itself, has rarely stood still.
But nowhere have those trends shifted, evolved, and been scrutinized quite as relentlessly as in Korea. Here, golf fashion moves faster than fairway gossip, and consumers dissect brands with a level of discernment that can be both impressive and mildly terrifying. New brands are studied, judged, embraced, or dismissed with startling efficiency.
The result is a consumer base with one of the sharpest eyes for quality and authenticity anywhere in the world. It is difficult to quantify, but easy to recognize. Clean lines without trying too hard. Luxury mixed with utility. Trend awareness balanced by restraint and purpose.
It’s golf fashion shaped by one of the world’s most style-literate cities, something I like to call Seoul Sensibilities, referring to the taste level forged by a uniquely competitive environment.
And increasingly, global brands have noticed.

Many golf brands in Korea have their own flagship shops dedicated to apparel only
Titleist understood this years ago, when its apparel business in Korea took on a life of its own under new ownership and local direction. What had once been a straightforward extension of an iconic equipment giant became something sharper and more premium. By going all in on the serious Tour-player look (I couldn’t even fit into their XL sizes), Titleist struck the right chord with Korean consumers and helped its fledgling apparel business break into the mainstream. Titleist became a household name even for non-golfers who wore its caps, shirts, and windbreakers in daily life. In many ways, it proved that even heritage golf brands could carry real fashion credibility when viewed through a Korean lens.
Several years later, PXG took a page out of Titleist’s playbook and followed suit. Korean consumers helped transform the brand from one known largely for irons and loud commercials into something broader and more stylish. PXG apparel’s growth in Korea was explosive, where it found an early audience and turned the category into something more than mere logo merchandise. It is still hard to walk anywhere in Seoul without seeing its palindrome logo.
Malbon’s meteoric rise in the United States was genuine, but its ascent into a global golf lifestyle brand owes much to Korea, where it was elevated by a market already fluent in modern golf style. Korea did not simply embrace Malbon. It pressure-tested the concept, refined its appeal, and helped push it into the global spotlight.
As such, new brands may arrive from abroad, but more often than not, their sharpest evolution happens here. If a brand can earn credibility in Seoul, it’s deemed to have passed one of the toughest style audits in the game.
That is why the next meaningful chapter may not come from outside, but from a Korean brand moving in the opposite direction, carrying those Seoul Sensibilities outward as K-pop once did.

Play young Stay dope.
From Seoul, With Intent
Khalhon is a label that feels less like a trend-chasing newcomer and more like the product of a market that has already seen everything. Golfers here have long been surrounded by luxury logos, technical fabrics, and tour uniforms disguised as lifestyle wear and vice-versa. In other words, novelty alone rarely lasts here, and the Koreans seems to understand that instinctively.
Its style language leans into clean silhouettes, relaxed but tailored proportions, muted palettes, and premium materials that speak quietly but confidently. There is a modern city aesthetic running through it all, with strong layering pieces, thoughtful textures, and subtle branding that suggests sophistication rather than demanding attention.

“Built for the course. Designed beyond it.”
Most importantly, the garments seem designed to blur the line between golfwear and everyday style. Shirts, trousers, knitwear, and outer layers move comfortably between a game of screen golf, a lunch reservation, an airport gate, or an afternoon coffee in Gangnam with friends.
It raises the question of whether this is golfwear that happens to look good off the course, or everyday clothing that performs beautifully on the fairways.
Personally, I have long appreciated Nike Golf for its clean, athletic modernization of golf attire. It also has the useful side effect of making me look like a more serious golfer than I probably am. But off the course, there are times when being instantly identified as the golf guy in a crowd of non-golfers can feel a touch self-conscious.

“Built for the course. Designed beyond it.”
That is part of what drew me to Khalhon, which seemed to blend golf and everyday wear naturally. While some of the outfits may be slightly beyond my personal confidence level, the brand also offers tasteful options for older guys like me who still want to express a little personality without regretting the decision later.
These are not simply flashy outfits worn on the course and then banished to the closet until the next tee time. They work surprisingly well off the course too, and I suspect many of the pieces will still look right a couple of years from now, which would certainly be kinder to my wallet than most golf fashion trends tend to be.
And perhaps that broader lifestyle positioning also helps explain why someone like Sean Wotherspoon would find Khalhon creatively interesting in the first place.

“Built for the course. Designed beyond it.”
“Korea is not only one of the most fashion-forward golf markets in the world, but one of the most fashion-forward markets globally. Korea is ahead, and I love to watch and try to catch up.” – Sean Wotherspoon, Creative Director at Khalhon
Seoul and Beyond
If Khalhon’s rise says something about where Korean golf fashion is today, its relationship with Sean Wotherspoon says even more about where it is heading.
For readers less familiar with Sean Wotherspoon, his arrival at Khalhon is not some routine celebrity endorsement or influencer collaboration. In design and streetwear circles, Wotherspoon is regarded as one of the more influential creative voices of his generation, particularly when it comes to blending nostalgia, storytelling, and contemporary culture into products that people can connect with.
He first gained widespread attention through his now-famous Nike sneaker collaborations, where his vintage-inspired designs and instinct for color helped turn him into one of the defining artists of the late-2010s sneaker era. His work gradually expanded beyond footwear into apparel, automotive collaborations, collectibles, and broader lifestyle design.
Modern golf style now extends well beyond the fairways, where performance and functionality are largely expected by default. And while plenty of brands already make technically competent golfwear, Khalhon seems more focused on designing clothes people would genuinely want to wear even after the round ends.
And when guys at Wotherspoon’s level show genuine interest in working with a Korean golf brand as its new Creative Director, fashion circles tend to sit up and pay attention. There’s already a huge buzz among the fashion-conscious here about upcoming collabs with iconic sports stars and brands.

“My creative direction for Khalhon is disruptive, colorful, nostalgic, and modern. My goal is to blend these avenues seamlessly within each collection.” – Sean Wotherspoon
In chatting with Sean, what stood out most to me was how genuinely energized he sounded about the project itself. Despite having already worked across and countless other creative spaces, he described golf as a completely fresh category for him, saying that Khalhon “will be an amazing vehicle for my design work.”
At the same time, his enthusiasm seemed tied just as much to Korea itself. He spoke openly about admiring Korea’s fashion culture while repeatedly insisting he is still a terrible golfer.
There was something oddly refreshing about that humility. Rather than sounding like a celebrity parachuting into golf simply because the category suddenly became fashionable, Sean sounded genuinely curious about what Korea might do with the category next.
And perhaps that is what makes Khalhon feel interesting right now. The brand feels less like a trend-chaser and more like the natural result of a market now confident enough to export its own point of view.
For years, global brands came to Korea to sharpen their image against one of the most discerning audiences anywhere. Now, a Korean label appears ready to send those Seoul Sensibilities outward instead.
Which brings us back to kkot-saem-chu-i.
That final cold snap before spring always arrives with a reminder that seasons are changing, whether we notice it immediately or not. Golf fashion feels a little like that right now as well, as the old boundaries between sport, streetwear, luxury, and everyday style continue to soften.
And somewhere in Seoul, a Korean golf label already seems prepared for whatever season comes next. I just hope they have everything in my size.

Little known fact: A putt that skips goes very straight. Air has less resistance than the ground. Speed is determined by force and loft at impact.
“True roll” is a BS marketing term used to sell stuff.

How does this device differ from SAM Putting Lab? Anyone know?
Brian
Jan 30, 2015 at 6:23 am
Quintic is different from SAM because nothing attaches to your putter. It reads the putter as well as the ball roll. While it is important to have a proper putter it is still more important to be able to roll the ball on the intended line consistently with a consistent roll. This system shows lots of data that relates to both.
MGolfer
Jan 30, 2015 at 12:06 pm
SAM reads the direct 3D movement of the putter with highly accurate technology. So all aspects of the full movement can be analyzed.
For the ball roll the SAM only does a estimate on how the putter face comes to the ball. There is a spin and direction prediction which is based on the physics of contact of putter face and ball.
The Quintic also can measure parts of the putter movement with the extended software package. Difference to SAM is that the analysis is based on a sticker on the putter head and image analysis algorithms. This will allow quite good readings for position and maybe loft. But for face angles or path or lie the accuracy will be not as good as SAM. Also the putter can only be analysed in the view of the camera – which is limited to a short range around impact.
The ball roll is very important for a good putt. However, the putter movement is what controls the ball roll in the end. If you want to improve this you need the full picture of the putter movement to know what to change. Optimized putting stroke will automatically lead to better ball roll.

^ this is exactly it. A camera based system from the side doesn’t capture the whole picture. When the ball is not directly in front of the lens then what? I’ll take a Puttlab any day over this infomercial.

There is nothing quite like the acid test of placing a club in your bag, which is why I have decided to go the old-fashion way of putter fitting and purchase a bunch of cheap old classics of high quality and various styles to see what type fits me the best. I’m also doing the same for my irons and shafts.
I find in the store or in a booth feels different from the course and driving range, and as such the results are not accurate.

Guys,
We appreciate the early feedback. However it is important for us to mention that this article is not designed to promote our facility, it is the first of a 4 part series on how our technologies can help the average golfer. This article is just the introduction to how we at Modern Golf use Quintic Ball Roll technology.
We appreciate you taking the time to read the article and we look forward to hearing your feedback on the remainder of this series.

I’m confused…
Is this an advertisement? If it is, it’s not a good one. I’d at least get the door leaning against the wall out of the picture and maybe have a club-fitter in the picture???
Is it an article? If it is, it’s very poorly written and wrx needs to step it up.
Quintic is very cool tech, but it’s obviously not solving this guys problem of his eyes way too far over the ball! Maybe he should get a lesson and not a fitting.

I’ve seen quite a number of golfers with strange putting techniques and lots of confidence hole out from everywhere. I do believe putting is something personal, subjetive and the right technique works fine to become an average putter.
Good putters are above all confident on the green and they repeat the same swing over and over.

While this is a glorified commercial posed as journalism, I think it’s good information. I just got fitted for a full bag last month after 4 years of playing. The putter info was most helpful. The fitter bent my putter so that the ball rolled pure off the face without any skipping. And told me that I need a 45 degree too hang mallet. Good luck finding those!
Get fit. Anywhere that is reputable.

Brian – Ping makes putter that fit straight all the way up to strong arc (large rotation putters). Technically a mallet with that much toe hang will very hard to produce due to the CG of the clubhead being further from the face.
