Mangum's Dragon Tail Fly Pattern- This pattern was designed to catch the largest, pickiest tarpon. And.... it works. Since this pattern was conceived, it has been used to catch just about anything that swims from tarpon to stripers to largemouth and smallmouth to musky and pike. It utilizes a head that moves water and allows the tail to move and dance. Equally impressive, is how the fly behaves when it is sitting in the water. Even when not moving the fly undulates and swirls, making it hard for fish to refuse. Designed from the new, innovative material, Mangum's Dragon Tail, which was created through a collaboration between renowned guide, angler, and tyer, Captain David Mangum and The Orvis Company. Size 1/0. Imported.
