Callaway Big Bertha Fusion driver review by GolfMagic READ: CALLAWAY BIG BERTHA FUSION DRIVER REVIEW Tweets by GolfMagic Comments tom-333 replied on Sat, 29/10/2016 - 20:27 Permalink Great idea from Callaway So good to see a manufacturer providing a shaft length more appropriate to amateurs . Hopefully others will get on board to provide extra choices. I would like to see ping do something similar . They work closely with UST with their shafts. So a shorter stock option would be easy to introduce.
