Isaac Buckland –
Used this pattern on a clear morning stream and saw a trout take it on the first cast. The movement and color match the real insects perfectly. Great for when the water is moving steadily.
Alan Piper –
Felt like a natural insect in the current. The CDC and biot blend well, and it stayed on the surface without sinking too fast. Works well in mid-stream sections.
Claire Dowd –
Highly effective in a technical section of a river. The trout were cautious, but the pattern fooled them with its realistic shape and movement. Would recommend for precise presentations.
