By the way, here is a recipe for a very good 'Coffin Fly'. May come in handy. It's a recipe I learned from Larry Duckwall.

Hook - dry, size 10 1xl
thread - white body, black head
tail - black hair (bear, calf or similar)
body - Dall sheep, spun and clipped
wing - same as tail
hackle - silver badger (2 or 3)
