RE:worm fly pattern?
I have never used this pattern, but it comes from the recent CCA presentation jack Gartside did.
He uses a small 1-2" pattern, similar to a wooly bugger. it is rootbeer colored, has a marabou plume tail and basically a crystal chenille body palmered up to the hook eye. That's it. He called it a clam/shrimp fly. Interestingly, he fishes it all year in estuaries, not just for worm hatches, and has apparently taken a few cows on it.
Sorry I don't have a picture or actual recepie, but if you get a hold of one of Gartside's books, I'm sure it's in there.
I believe Ken Abrhames has a worm pattern in his book as well...
