Originally developed on the Bow River in Canada, this pattern tied with a conehead for extra weight and movement, is deadly on large trout all over the world. This particular version is tied with a large, black conehead and black and white legs. Works well in all types of water conditions. Size 6 hook.
TIP: Tie to your tippet with an open loop (i.e. a perfection loop or a non-slip loop knot) to give the fly more movement.
