This pattern was originated for heavily pressured England stillwaters, but trout in the US and BC love it also. The foam eyes make the fly buoyant, which allows for a completely different presentation from what other anglers are likely doing. They also cause the fly to swimerratically on the retrieve which drives the fish crazy. Fishing on a floating line to get the most savage takes you’ve ever seen, or fish it on a sinking line and catch the biggest fish in the lake. It’s up to you.

Top contender for best fly name ever.
