Very nice tie, Byron!
The Crackleback is a fantastic fly. I've had good success with it on small mountain creeks in NC too.
Not to take away from this thread, or the fly itself, but I'm amazed at all the different names and credits to basically the same fly. Orange Palmer (and yellow too), Orange/Yellow Asher, Crackleback, Bivisible ....even a larger Griffith's Gnat. Yeah, a couple of them may use a little different material for the body and a rib on top or something, a tail maybe, but they are all basically tied the same.
