Just purchased a set of AP2 714 irons 5-PW with Dynamic Gold S300 shafts. I am very happy with the set and am playing very well with the irons. My problem is tendonitis in my left wrist and arthritic issues in both hands. I am 51 years old and have been thinking of switching to graphite to alleviate some of this pain I deal with every year. I am thinking of sending the clubs back to Titleist to have them re-shafted but am looking for suggestions as to which shaft would still provide the same or similar ball flight that I experience now. I have a medium trajectory with a slight fade. Any suggestions?
