Overview
This Curtis Fry/Fly Fish Food tutorial features Herb Patterson's original design that incorporates subtle flash from the mylar core beneath the mohair wrap. The mohair fibers provide movement while the underlying mylar adds just enough flash to attract fish without alarming them. Some modern tyers substitute Arizona Simi Seal dubbing for the mohair to simplify construction.

Fishing Tips
Season
Year-round stillwater effectiveness with the mohair providing movement even in cold water when other materials become stiff.
Presentation
Fish under an indicator or with slow strips on sinking lines. The mohair fibers undulate with minimal movement, creating lifelike action whether drifted or actively retrieved.
When to Use
Select this pattern as a reliable searching fly in stillwater or when trout are keyed in on leeches. The subtle flash often triggers strikes when solid-colored patterns fail.
Water Type
Designed for stillwater fishing in lakes, ponds, and reservoirs. Effective at various depths depending on rigging and line choice.
Rigging Suggestions
Fish on 12-15 foot leader with 4X-5X fluorocarbon tippet. Use floating line with indicator for shallower presentations or sink-tip/full-sink lines for deeper water.
Visibility & Floatation
The mylar core provides subtle flash visible to fish without creating unnatural reflection. The bead ensures adequate sink rate to reach cruising trout.
