We’ve reached the point where one fairway wood isn’t just one fairway wood anymore. Callaway’s Big Bertha Alpha 815 fairway woods have two adjustable weights in their soles that allow them to perform like two completely different clubs.

Position the club’s 30-gram weight in its front weight port and its 3-gram weight in its rear weight port, and it will create a lower-spinning ball flight. Flip the orientation of the weights, and the ball flight will have more spin — and the club will have more forgiveness.

Think of the heavy-weight-forward configuration as the fairway wood equivalent of Callaway’s Big Bertha Alpha 815 Double Black Diamond driver — its more forward center of gravity sacrifices some forgiveness for less spin, which can create more distance for some players.

The 815 fairway woods have a compact shape that was inspired by Callaway’s 2014 Big Bertha Pro fairway wood, a tour-only product that was used by several Callaway Staff players including Patrick Reed and Gary Woodland. You don’t have to be a tour player to use the 815 fairway woods, but better players will see the most benefit from their smaller, tour-inspired head design — particularly in the lower lofts.

The 815 fairway woods use Callaway’s Forged Hyper Speed Face Cup that improves ball speed on shots struck across the clubface. They also have Callaway’s OptiFit Hosel, which allows golfers to choose one of eight loft and lie settings.

Does the technology work? In my testing, the heavy-weight-forward configuration created a very impressive 800 rpm less spin than the more forgiving configuration. Not all golfers will see that big of a difference, but the combination of the 815’s adjustable weights, adjustable hosel and three different loft options makes custom fitting (and tinkering) a breeze.

The Big Bertha Alpha 815 Fairway Woods ($299 — in stores Jan. 16, 2015) are available in lofts of 14, 16 and 18 degrees. They come stock with either Fujikura’s Motore Speeder 665 shaft (L, R, S and X flexes) and Aldila’s Rogue Silver 70 (R, S and X flexes).

Testing Tips: Golfers with very fast swing speeds (105+ mph) will want to try the 16-degree model with the heavy weight forward. For me, it launched extremely high because of its 4-wood loft, but had a spin rate that was similar to a 12-or-13-degree fairway wood.

Lower-swing-speed golfers, or those who use two fairway woods, will want to try the 14- and 18-degree models with the heavy weights back.

Big Bertha Alpha 815 Hybrids

Callaway’s X2 Hot hybrids woods swept our 2014 Gear Trials: Best Hybrids list, earning awards in our Distance-First, Forgiveness-First and Balanced Performance categories. One of our few complaints? They weren’t adjustable.

Callaway’s new Big Bertha Alpha 815 Hybrids are adjustable, and like the X2 Hot hybrids include a Forged Hyper Speed Face Cup for top-notch ball speeds. They’re most similar in design to Callaway’s X2 Hot Pro, with a compact shape, minimal offset and a low, forward center of gravity for a penetrating trajectory.

The Big Bertha Alpha 815 hybrids ($249 — in stores Jan. 16, 2015) are available in three lofts: 18 (2H), 20 (3H) and 23 (4H). They come stock with Fujikura’s Speeder 865 shaft (R, S and X flexes).
