Hannah Turner –
Used this fly during a morning hatch and it stayed on the surface perfectly. The olive color and body shape matched the actual caddisflies. Very effective when the water was calm and the wind was light.
Blake Lawrence –
Felt like a natural match for BWO hatches. The fly floats well and doesn’t sink. I caught several fish with it on a slow-moving stream.
Melanie Ross –
Good imitation of olive caddis. A bit stiff when first tied, but after a few casts it settled into a natural position on the water.
Megan Forsyth –
The detail in the wing profile and body segmentation is impressive. I’ve used it in both spring and summer hatches and it’s consistently effective.
James Simpson –
Works well in moderate wind. The fly stays on the surface and doesn’t get lost in the current. Slightly more expensive than others, but worth it for accuracy.
