We had to Revised the Heavier Callaway Aftermarket Weights for the New 2017 BBG Epic Sub Zero (Driver Only) & Fusion Fairway and Last Years Versions 2016 GGB Double Black Diamond, the XR 2016 Sub Zero, XR Pro, Great Big Bertha 2015. We are making the heavier weights in Tungsten, because the old-style shank was too Long and didn’t fit some of the lower profile heads, they now fit all of them with no problem. The Tungsten weights are little more money but worth it.
They are available in 2, 4, 6, 8, 9.5, 11, 13, 15, 17 Grams which is more than the factory is offering. With many different head weights, you have combinations for Fade, Draw and Swing Weights Adjustments.
