Dave Hise is a great friend of mine - we've broken bread and consumed the finest of whisky's together. Still, I don't hesitate to call him a dirty-ass worm dunking son of a bitch for inventing this pattern, but hey - friends are friends, and the monster fish he chases eat them. Ask April Vokey about it....
I believe it's a pattern modeled after the "cinder worm". I just moved to South Carolina and the boys at the fly shop in charleston told me about this somewhat infamous hatch. When it happens, it's the only thing the fish are keyed in on. Pretty weird.
I guess I don't understand what's actually wrong with this. I tie a variety of flies - some emulate various life stages of insects, some emulate bait fish, and some, well, not really sure what they emulate, but they still work. I tie a variant of this myself - right down to the bit of flash, and have had success with it at times. If it's legal (i.e., not scented, barbless hooks, within size limitation, not natural bait, etc.), does it matter? The fish don't seem to care.
Whatever works, good sir. No "high horses" here. One of my favorite scenes in "low and clear" was when xinie was giving JT guff about catching steel on the swing. So funny. So true. Fly fishing is deeply personal so fish in a manner that makes YOU happy.
