I moved from an old set of cobras, to these recently. I havent lost any yardage from 3 - 8 iron but compared to the cobras, 9, pw are not as strong. Which does me a massive favour really - now at sub 130 yards I have a choice of clubs I can use rather than a 3/4 wedge.
Feel wise, well lets put it this way - I can now feel the shots. They set up great, nice and sleak looking. I find it easier to control the ball and move it both ways.
To be fair there isnt much difference between the mp32s and the mp60s, if anything the mp60s were slightly more forgiving - but I prefered the visual aspects of the 32s.
I wouldnt reccomend the 32s if you are a higher handicap though, catch anything not in the sweetspot and the ball will drop like a cheap whore. Catch the ball out of the middle and the ball goes like a rocket.
