Yes I still play them, and plan to build a combo set with 4-6 Ap2 and 7-PW 710 CB.  I don't see the point in going with 710 AP2 as most people will tell you they are very similar.  I currently have Project X 5.0 flighted and like them but the CB's I have bought have KBS Tours stiff in them which in intend to soft step once. 

I have been playing these AP2 irons for almost 2 years.  I really like them and not sure that I will get the new AP2 anytime soon.  I have not hit the new irons but understand that there is not much difference from the old model.

I agree,

I have the exact set you are looking at.  Same shaft and flex and hands down, they are the best irons I have ever owned (and I have owned a lot!!).  Only reason I am considering a upgrade this year is because mine are getting beat up after a few seasons of play.  I would definitely pick them up if they are the right price, you won't be disappointed. 

I have had the original AP2's since the summer of 09'. I love them.I have PX 6.0 shafts and my set is 3-P with 2 vokey wedges. I am a 3 handicap and they work perfectly for my game. What are the specs for the clubs your looking at? Also, what is your handicap?
