Let it snow......
I'm looking to upgrade my stock stiff Phenom shaft in my R1. I won't have the chance to test either of these in the R1 head. Has anyone hit either the Kiyoshi White or the AD-DI 6 in an R1 driver? Just your opinion on each would help me even if it's in another club. I have a smooth transition at the top and a SS of 107. Thanks for the advice!
