I would guess almost everyone knows what wedges are and what they do, what about reverse wedges? 

Rather than raise the grips and change the angle to flatter, why not lower the grips and give them more droop?  Especially if the grips have already been raised thru the use of risers.

I love my C14, but I would prefer the grip position of the C10-IMHO the grips on the C10 had more droop, which put my elbows at a more natural position.  More street bike, less dirt bike angle.

I don't have the knowledge or equipment to make some reverse wedges, but if somebody does, but doesn't have a set to use as a pattern to get started, I have a like-new set I've tried and am not using now.
