Wooly buggers are probably one of the most popular and versatile streamer patterns ever tied. They are effective on such a wide variety of fish, from freshwater to even saltwater, warm water to cold water. Almost every fly fisherman has a few wooly buggers in their box. The Crystal Bugger is a variant of the wooly bugger, and it is a bit more flashy. It uses a flashy type chenille to attract fish in more dirty water.
