Carl Simpson –
Fished it on the Bow River during a heavy rain. The double bead kept it in front of the fish and the two-tone look matched the natural worm pattern well. Got good strikes, especially in the middle of the run.
Wendy Morrison –
Works well in high water. The weight helps it stay in place, and the profile looks realistic. A solid addition to my San Juan fly collection.
Abigail Paterson –
Used it on a cold stream with whitefish. The fly stayed in position and triggered several takes. The design is accurate and the action is natural.
