I purchased a set of AP2 irons 2 years ago from a golf retailer. They were fit to me, the shafts are project x 5.5, they were lengthened and lie angle was changed to match my height. I immediately lost 10 yards off every club from my previous clubs which were over 15 years old with dynamic gold S300 shafts. I went to a Titleist club fitter and he recommended changing to the Nippon 105T (stiff shaft) and keeping the length and lie angle from the previous club fitting the same. Is this a good change? I already hit the ball high with all the clubs, the 105T has a lower kick point and I think will only make me hit the ball even higher. From what I have read the project x 5.5 weighs 115 grams, the 105T is 113 grams. Is there a real advantage to losing 2 grams and having a lower kick point. Not sure I see the advantages to making this change in shafts. Any advice?
