I know this isn't the answer you are looking for but I think you would be better off getting fit for a set of Edel wedges. See the link to the Youtube video below. It has Mike Adams and David Edel explaining their new wedges and how they differ and standout from the other wedges on the market.
They use an 8 grind system with wedges ranging from 10-20 degrees of bounce! Most players don't use enough bounce on their wedges, and many manufacturers don't create wedges with that amount of bounce.
They also created the wedge to have grooves that extend towards the toe of the club where most good pitch shots are struck (the ball rides up the face and towards the toe). With traditional wedges the toe is void of grooves to capture the spin on these shots.
They also align the center of gravity with the center of the club and the sweet spot. This allows for shots struck dead center to fly more predictably. Normal wedges the center of gravity is towards the heel (the worst spot of the club to hit a shot.
Sorry for not answering your question, but I would look into these a little before you make your decision.
Ask Erik. I think he could vouch for how great these wedges are!
