Jeff, have another look, for me, if nothing else. When you put the flat edge on the face, where does the bulge actually start? It's not humped, in the middle, is it (on all/any)? Are the faces flat except for the last 4-5 scorelines (from toe/topline)?
My AW shows what I just described, flat from leading edge to 5th line down at toe, and has got me wondering if they are not, in fact, supposed to be that way. What with a 'rebound' type face. And, it really couldn't be called a 'bulge' if this is the case.
