I am a low single digit and have just got fitted for new irons and the AP2's and MB's were the best. I am left handed and the place I went to get custom fitted didnt have some of the new irons I wanted to hit in lefty so they said when they come in (next couple weeks) I can go back and try them on trackman with no additional charge. The numbers on the AP2's and MB's were basically identical. So the big question is, is there really a reason in purchasing the MB's when all the numbers and the feel are almost the same with a more forgiving AP2?
