Last year I was fitted into Mizuno 925 HMP irons, 2* upright, KBS Tour Lite R flex shafts.  Love the feel and how they play.  Lately my shoulders have been feeling the effects of golf the day after I play, thankfully no issues swinging, and was considering giving graphite a try to reduce the weight a little and lessen the impact.

What should I look at as 1 to 1 (or close as possible) replacement in terms of profile and overall characteristics?
