Tied by Montana guide Bob Krumm for use on the Big Horn River and elsewhere.
Wrap shank with thread.
Tie in ViViva behind the bend and wrap forward. Use a finger over tying thread and wrap to make a short dubbing loop at the head. Insert a small clump of rabbit fur and guard hair at right angles to the loop and twist loop. Bob suggest using 2457 scud hooks rather than the thinner wire 2487 if you want to catch big fish. Also use lots of head cement to make flies that stay together.
