Found an old box of Swimming Nymph hooks and was trying to come up with something to do with them. After a failed attempt at a Flick Stonefly Creeper, gave this a shot. No better, no worse than the standard (although it is somewhat weedless), just playing around.
hook - Orvis 1512-00 #12
thread - MFC 8/0 brown
tail/shellback - pheasant tail fibers
abdomen - UTC wire brassie/brown x-fine/copper
thorax -peacock herl
wingcase/legs -pheasant tail fibers
Part 1
mash barb and attach thread at 60% mark and wrap back to bend
tie in a clump of pheasant tail fibers; fold butt ends back and wrap to the rear
take 2 strands of wire, flip hook (rotary makes it a lot easier) and tie in on underside of hook
wrap wire back to the bend
take a few wraps of wire (try to keep the 2 strands tight together), pull the pheasant tail butts over the back and secure with the copper wire
