Received my AP1 712s on Friday after fitting/ordering w/ a Titleist Advanced Fitter (Roger Hatcher at the Golf Tour Trailer at 1757 Golf Club near DC). I took a risk and played a round w/ the clubs the next day instead of getting used to them through range sessions beforehand. Clubs were great -- I had complete confidence in them after two shots, and never looked back. As a high handicapper whose previous irons (Taylor R9s, and previously R7s and RAC OS2s) all felt too light, these AP1s were fantastic w/ the Dynalite Gold XP shaft. Thank you Titleist!
