pb1711: Can I ask what you do for shots around the 107-110 yrd mark?
I too was used to applying backspin on my wedges prior to getting the higher level CG's - on word for most players : DONT (or use very sparingly). For the 107-110 shot you describe, the 56 Cleve rated 100 full shots to 105 Nike/Callaway)- with topspin, it will go an average of 108. It is also, like all Clevelands, very accurate on partial shots - and unlike any other wedges on here rough is meaningless to these babys. Once you learn to pitch and chip with em, watch out. Since I got these my go to short sided shot is no longer the flop either. I had a hard time giving up my trusty Satin (64) but learn the CG 64 and you won't need it anymore, plus you won't have a gap if you get the CG 56, 60, and 64. The latter punches 50, and you can be very accurate on partial shots down to 50% (25 yards on punch). I just holed out a lovely partial punch on Kiawah back 9 par 5 from 36 yards. Same hole a few days ago, I back-spinned the 64 into the hole for another eagle.
Get em - learn em - its worth it!
