This fly has caught a variety of species. From Channel Cats and Carp to trout and Waleye. One of my most productive patterns. Can be tied in any color or combination of colors. Most productive are olive, black, and brown. In a combination tan, with red throat and olive bronze head. Some of the fish caught, 39 inch Channel Cat, 35 inch Carp, 19 inch Smallmouth, 28 1/2 inch Walleye, and a 41 inch Pike. A great overall pattern.
