Features of the Gray Drake, Comparadun
The Gray Drake Comparadun provides a great mix of lifelike silhouette, visibility, and buoyancy.
Many Yellowstone area fly fishing guides go straight to comparaduns when a hatch brings up actively rising trout.
This fly pattern floats in all but the fastest and roughest stream currents and trout seem to prefer this fly to many of the traditional hackled patterns.
Fly fishers around the world should consider this a staple fly where large gray mayflies are present.
