Hi, I am a 10.3 handicap who pars/birdies 10 of 18 holes with a triple and couple of double always thrown in. Currently, I hit G15s with the Z65 shafts (no clue how much they weigh). I got fit yesterday by a Titleist rep and he recommended the NS Pro 970 shafts for me with the AP2s. As a retentive guy who fixates on things like this: I'm pretty sure the 970s are much lighter than what I am used to. What impact does a lighter shaft have on my game and ball flight? They felt great and I hit them more solidly during the fitting than I did the Dynamic Gold and the KBS shafts. But when I hit solidly, I couldn't really tell the difference in ball flight although I did feel the heavier shafts were more work. I have used my neighbor's AP2 710s with the NS Pro 970 shaft and I love them, so I'm worried for nothing I think. Thoughts? Thanks.
