As a general-purpose streamer, this is a superb fly. It is useful in lakes and in slower portions of rivers. This large profile leech pattern will get attention from a distance. Cross-cut zonker-style rabbit strips give this fly a life like pulsating action proven to stimulate strikes from trout, salmon, bass, and a variety of other species. If you need to get down to suspended fish, or fish on the bottom, this Leech is the perfect pattern.
