I have 2 CG12 Black Pearl wedges and love them. The dark face is particularly nice on ultra-sunny days. I can't remember what my sand wedge is, but it's a Cleveland too (I destroy 56* wedges from being in the traps too much and chipping with SW).
I could be wrong on the zip grooves, but I think they will be allowed for amateur golf through 2014. They tear up golf balls fast, but it does make it easier to bite on hard greens.
The Titleist Vokey wedges are pretty good too, but I find them to be much less forgiving than the Clevelands.
You should try to find a place with an indoor hitting mat and try them all out. The weighting of the different wedges (not to mention bounce rating) will make them feel and play differently. If there is a Golf Galaxy near you I'd check it out, maybe you can even find used wedges for half the price.
