Corbo, here are a couple of variations i like on the traditional BHPT pattern.
Grizzly hackle palmered through the thorax
White floss, hair, or any other material pulled over the wing case and tied down at the bead. I think it gives it the air bubble effect that Walter Babb uses on his George Nymph.
I don't have a picture handy, but the "Double Standard" nymph has become one of my favorites and is really easy to tie.
