A couple of years ago I was looking at getting a new set of irons. Been looking at the Titleist 735cm's but figured that was way too much club for me. So I kept hitting different iron brands from Adams to Zevo's. Then at my club a guy decided he needed to get a set more for a senior and decided to sell his 735cm's. So I said the heck with it and picked them up for a nice price. All I can say is I wish I would have gotten these before! The set up was clean, they framed the ball like I thought a golf club should, and as far as forgiveness well they were not nearly as harsh on mis-hits as I thought they would be.
Since then I have hit a number of "players" clubs and some are more forgiving than others but I didn't see the "night and day" difference between players and game improvement. The biggest difference for me was the distance. I would say I am a half to a full club shorter with the 735's than a game improvement but the accuracy especially with the short irons is much better. Maybe I have just convinced myself of the "truth" but I feel if the club looks right and frames the ball that gives you confidence well that's your set.
Just my two cents.
