I really only have 1 set of clubs to compare them to, and that is my Titleist DCI 962's....
I played 36 holes today.. 18 in the morning and 18 in the early afternoon...
I found these clubs to be more forgiving that my older 962's... For example, as a mishit, I would hit off the toe... On the 962's the hit felt harsh in the hands and the ball would generally go right...The AP2's were a lot more forgiving. I ended up alot nearer the green than I would have expected, and the hit didnt feel very hard to my hands..
A well hit ball was had a muted feeling in the hands compared to the 962's, but I could still tell a well struck ball... Just that the feeling was more pronounced with the 962's... Ball also got up just a bit better.. more hitting needs to be done for me to give more info on that..
I had what seemed to be an easier time hitting balls from the rough...With my 962's, the club face would get opened up by the grass, causing a nice slice... With the AP2's, I felt like the club face powered through the rough better, helping me keep the club face inline...
I also gained some distance.. with the 962's I was hitting a 6 iron about 160yds.. now it seems i am in the 175yds + area... Not sure yet.. still feeling them out on distance...
I encountered a problem that I didnt have with my older irons in that my short irons, 7-pw, I had a draw going on. Not sure why yet. Sometime the draw was more of a hook..
