Warren Buckland –
Fished in a fast stream during fall and got multiple strikes. The tungsten bead drops quickly and the realistic coloration made trout react immediately. A reliable pattern for deep water fishing.
Katherine White –
Good for spring fishing when stoneflies are present. The fly sinks fast and feels responsive on the line. A bit heavy for light tippets, but worth it for larger trout.
Jason Chapman –
Used it in a deep run section of a river and caught a large brown trout. The design mimics natural stoneflies well and triggers aggressive strikes.
