Hi guys. I'm thinking about picking up a 917 F2 this fall, but I'm not sure what shaft would fit me. I have a graphite design Tour DI-7 stiff flex in my driver, and love it. I've always had a hard time getting high enough launch in fairway woods. I'm currently playing a 913 fd 18 degree with the rip phenom 80 stiff. I would like to get the 16.5 degree head in the new one. Any thoughts on something that might feel similar to the DI7 but would launch it higher? I've always used 80 gram or heavier shafts in fairways. I'dbeup for trying something in the 70 gram range, but have always disliked the feel of lighter shafts. Any advice would be appreciated.
