Tour Edge Exotics mini driver review + TaylorMade Spider ZT Max first look – Club Junkie
GolfWRX’s Resident Club Junkie, Brian Knudson, was naturally excited to get his hands on Mitsubishi’s new Diamana WB shaft.
In this video, BK gives you a brief overview of the new WB, builds up a driver, and takes it to the course for some testing.
With the rebirth of the iconic Whiteboard profile, Mitsubishi didn’t just re-issue a classic, but rather infused all the company’s latest tech into a new shaft, paying homage to the original with its quintessentially Hawaiian-inspired stylings. A summary of that impressive roster of technology, below.
- 80-ton Dialead pitch fiber: Positioned in the handle, Dialead is designed to deliver greater ball speed via better energy transfer.
- Aerospace-grade MR70 carbon fiber adds additional strength, and 46-ton fiber in angle plies in the tip section reduce torque for tighter shot dispersion.
- Consistent Feel Design: Engineers target minimal variance across shafts (butt OD, weight, and balance point) to make the fitting process easier.
- Xlink Tech Resin System: Engineers continue to reduce resin content and increase carbon fiber volume for greater feel without sacrificing strength and durability.
Equipment
Neal Shipley, AKA, the “Big Fridge’s,” custom stamping
Neal Shipley was the first to admit that he enjoyed his food while in college. But since his days at Ohio State, he’s slimmed down and earned a PGA Tour Card.
That hasn’t stopped him from having fun with his wedge stampings, though it’s led to some misunderstandings.
On the 54 (degree), we have ‘Big Fudge,'” Shipley told GolfWRX. “It was supposed to be ‘Big Fridge,’ so this happened a little while ago. ‘Big Fridge’ was a nickname between my college teammates and I, with ‘fridge’ meaning stomach, a big stomach.

“We told the Ping guys to put … ‘Big Fridge’ on it, and I think maybe some bad cell service or something, and they thought I said ‘fudge,’ so they put fudge on it.”
On Shipley’s 50-degree he also continues the food theme, this time with his go-to order at the “Golden Arches,” and his stamping “DONS 7.”
“The number 7 meal, the two cheeseburger meal, that was my McDonald’s order, back when I would have McDonald’s frequently,” Shipley shared.

As a long time Diamana fan this excites me. Kind of makes me wish I held out on buying a few shafts recently.
