McKnight's Fat Boy Chernobyl Ant
This thing just straight up fishes. I think its the wing color and the overall tones of the fly. It floats great, carries a dropper very well, and hooks fish. We like it for a stonefly on our rivers, but it makes a great general hopper/attractor on any stream. It is a little hard to see in flat light because of the grey wing, but that is probably what makes it so fishy in direct sunlight when other flies like Chubby Chernoybls are not as effective.
