The only one I've done serious reprofiling to so far is my DMLE. It came with a 30 degree edge, and I took it down to a 23 degree edge.
Here's a couple pics; I've posted them before, but maybe you haven't seen them yet.
I can shave the hair off my face with it now. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
I'm currently working on reprofiling the edges on my Tan Sod, Yardkeeper LE, and my CG ASH1. When they're done, I'll have to put some pics up.
