Searching for a driver shaft that would best suit my game. On a launch monitor my ss is about 108mph with a launch angle about 9 -10 degrees. Spin rate is usually around 3100 rpm. Any suggestions on a shaft that can decrease my spin rate and increase my launch angle. traditionally I like a 70=75 gram shaft. Any suggestions? Not close to a dealer that can get the proper shafts for me to try. I am going to have to order one and see how it works out
