Last week I received my new AP1 714 irons that I had custom ordered with Project X 5.5 shafts at a +1/2 inch length and +1/64th grip. In October of last year I had shoulder and elbow surgery finishing my re had this March. Anyway after two rounds and two extended trips to the practice range, it's obvious that I made a terrible mistake in shaft selection. How do I go about having Titleist replace the shafts with a steel shaft in an R or firm R flex with a low to mid kick point still with an extra 1/2 inch length and the same grip size? Also what replacement shaft would TT recommend?
