I recently purchased a set of AP2 714 irons from a friend of mine. He currently has regular flex graphite shafts in them, but I am looking to reshaft them with stiff flex steel shafts. I am looking at getting the True Temper XP105 .355 shafts. The set is a 4-PW. I am just wondering what shaft length (not total length) each iron is. In other words, what length should the shaft only be for each club? I am looking to make them the standard length since that is what I am used to. Thank you for your help!
