I have been golfing now for my 5th year and am 62 years old. Got a late start and wish now I would have started a long time ago. I started out with a cheap set of older clubs and about three years ago got a set of Muzino JPX EZ Irons that I never hit very well, probably more me than the clubs. I now have a set of TM M2's, regular flex, and have a handicap of 14 and after playing 80 rounds with them seems that I am getting as good with them as I am going to get. Have always wanted Titleist clubs but want to make sure that this is the last set of irons that I need for awhile. Can't afford to buy a new set after this. I was fitted for my M2 irons as well. Just need some some advice on going to AP1 or the new AP3. I now hit my M2, 7 Iron average 132 yards.
