I switched from the Cleveland 56 and 60 RTX to the then called Mack Daddy wedges. (Same specs as the PM Grind) Slower meter to match my irons and better forgivemess was the reason. I like them. I did keep the Cleveland 64 as there is no PM Grind 64 available.
To remind myself the 64 has a faster meter than my other clubs I take a 'practice' swing with it before hitting the shot. LOL
Overall the change was good. now just need the 64.
Have fun and hit 'em straight,
