I recently tested the R11s and the RBZ drivers with a number of shafts. I am looking for a shaft that is low launching with low spin for one of these. I currently am swinging a 905r 9.5 with a v2 86x. I like my current driver but the carry distance on the launch monitor is around 280 with 3700rpms of backspin and launch angle between 11 and 14 with a ball speed of 165-170. I hit the RBZ with the stock x ok but the launch was around 18 and backspin around 3500rpm with a ballspeed of 160. I dont get it, I have a steep swing plan because of height. I was thinking about the ahina 70x. Any suggestions? Does Taylormade make a low launching low spin shaft? Thanks for your help!
