Kinda looks like a bead head Royal Wulff/Pheasant Tail; designed by Dave Hise. Original pattern calls for golden pheasant tail fibers for the body; the one I have was crap (didn't even know I brought one) so I subbed hen pheasant tail fibers and they seemed to work okay. Don't know if it works any better than a PT, but I like to break things up a bit if I've been tying a bunch of the same pattern.
