Mary Morgan –
This fly worked perfectly during a morning trout session on a calm lake. The way it floats on the surface and imitates a real mayfly made a big difference. I caught two fish in under 20 minutes.
Paul Glover –
Good quality and realistic appearance. It stayed on the surface well and triggered several rises. A solid choice for mayfly patterns.
Evan Springer –
Used it during a late spring trip and saw consistent action. The fly stayed natural and didn’t sink, which helped with timing my casts.
