I'm one that also had issues with the more lofted Cleveland wedges and 2what i considered excessive backspin.
However, I have been using the 56°, Lvl 76+ (100 yrd), CG16 for many months now.
It's to bad the TaylorMade Z-Satins are not longer available. I still use the Z-Satin Lvl 39+ 60° and 64° wedges, but have been unhappy with the 60° performance lately. So, I will likely be re-thinking which middle wedge I play.
