The wedges to a set might not match the type of courses you are playing. I play Ben Hogan
irons. They have the wedges that are for my set and the new Carnostie and the other new type escapes me now. I don't play Hogan wedges because they don't suit the courses I play.
I play Reid Lockhart a dual bounce setup 25* and 8* on the sand wedge. Plays either hard or soft. If you go to thegolfchannel.com and go to What's in the Bag. You will see most pro's don't play the wedges that match their set.
I would suggest asking to try other players
irons before you buy. Weight, feel, how the club looks when you open the blade (being able to find the new center) and being able to lay it open with the leading edge as flat as possible are some keys.
Wedges are your up-n-down
clubs. Don't skimp, they will save the most pars.
Keep it inthe short grass,
