Can a lady reply
What degree is your pw?
I carry 48*, 54* and 60* wedges. The former is my pw, the middle is my sw and the latter is my lw.
Wedges these days come with specific shafts in them. So whatever wedge you chose go with their suggested shaft.
This may sound funny, but, look is one factor for me when chosing
clubs. I suggest looking and trying a few brands. Whatever feels and looks good I suggest you chose.
I would steer away from gap wedges. Just a personal thing. That's why I have equal degree difference between my wedges.
Good luck.
