It is a great wedge, no doubt about it but I'm not yet convinced it's worth the extra money compared to the Z Satin. I've been using it for a while and still have some problems with half length shots, it's just not as linear as the Taylor Made. And while it's impressive watching a ball land and back up several yards it isn't always helpful. Most of the time I just want the ball to stop dead, the CG needs almost full t/s to do this, anything less and it backs up, particularly on full strength shots.
I'm still using it but often feel I'd be closer with the good old Z Satin. And for less than 1/3 the price too.
