The color combination sold by Umpqua is my most productive combo. I replaced the pheasant tail, with Coq de Leon for improved sheen, speckling and added durability. The natural pheasant tail body was swapped for dyed dun pheasant tail and uses Hareline's shrimp pink ice dubbing teamed with a red thread collar to create the hot spot. This color combination was solidified for me at my first World Fly Fishing Championship in Portugal, 2006. There I won a river session (basically catching the most total centimeters of fish in 3 hours) on the River Alva using the Frenchie and Bionic Ant in a dry dropper rig. I was sold. The fish in every country and state I've fished since have also been impressed with this fly. Tie some and fish them. Your catch rate will thank you.
