I tied this on a size 6 hook, which is a bit big for this fly. I would tie it mostly size 8 and 10. The photo only hints at what should be pronounced, the tail. It should have a layer of light olive marabou over an equal length of white or tan marabou. The body is sparkle chenille with olive and blue highlights. The rest of the pattern is straight forward Woolly Bugger. This pattern was first discovered by me at the Sunriver Flyshop, Oregon. Bob Gaviglio offered it as an excellent lake pattern and it has repeatedly proven itself, at some point, in every lake I have fished.
