Here's the recipe for Barry's Pike Fly:
Hook: 1/0 to 3/0
Thread: Color to match pattern
Tail: Rabbit strip and Krystal Flash
Body: Cross-cut rabbit strip, palmered
Best colors seem to be all black and all yellow, although I have a friend who swears by a yellow tail with a red body. The body is a rabbit strip, but it's cross-cut instead of the usual zonker style strips. This helps the hair to lay more naturally as the strip is palmered (i.e., swept towards the back).
