Kinda, it's a variation on the MOAL, or standard string leech... I don't weight it though, and I add the little "hootis" of rabbit hair at the head to add bulk... The Dollies and Bulls seemed to like it on the OP, so who knows?
I'm still working on mine. I just finished a batch of Skwala nymphs and dries for use later the next month on the Yak. I'll continue work on my sculpins this evening. I tend to push things off to deadlines, but I make 'em.
