I dunno prowlsta, you already have one of the best sets of
irons in history. If you are happy with them get them regripped. I had a set of Eye 2's once, wish I had never got rid of them.
You have learned to play the game with
Pings so I would suggest a good cavity back iron. Unfortunately
Ping have never matched the Eye 2, the next best are the ISI's preferably in Beryllium Copper.
Failing that try a set of Hogan Apex Pro they are similar to the whole
Mizuno MP-30,
Titleist 690CB idea, but a good bit better value for money. Personally I think Hogan are second only to
Mizuno in the quality of their
irons. The
Cleveland TA3's are fantastic as well.
If you are getting rid of the
Pings, give me a shout
