I did it! From different sets of AP2 iron since 2008 to a set of T200 irons. I had a fitting and the NS Pro 950 GH shaft works best for me. Similar to my XP95 shaft that i had in my last set of AP2s. The forged face feels good, they are forgiving and i gain more distance.
The 4 iron is still my AP1 but i think about a U510. I never hit one and like to test these club with different shaft, not only the Hzrdus smoke if its possible.
