I'm a senior with a 14 handicap who is a high ball hitter with lots of spin. The fitter put me in a 910D3 9.5 with a regular RIP shaft that has worked well for me. I'm distanced challenged so I have been playing a 910F 13.5 degree knocked down to 12.75 and a 10F 17 degree. . I still get a balloon into the wind on the 13.5. I am a sweeper and tend to hit most fairways thin. If I am hitting it low on the face would an FD be an option or should I stay with the 910F? Should I consider finding a RIP shaft for my fairways or stay with the kai'li that I have now. Any comparison of the 913's to the 910's?
