Looking at purchasing new AP 2's, replacing my old AP 2 710's. I had my swing speed tested today averaging 73 mph with a 6 iron average carry distance was 154 yards. The fitter suggested I stay with a s300 shaft, but everything I have read says that I should look at the r300. Really torn between the two. I am 58 years old, 9 handicap, hitting a slight cut. Looking for advice.
