The F-fly is by far my favorite dry! It’s absolutely the Walt’s Worm of dries. The F-fly is a great searching dry but (for me) shines as a small dry for light dry dropping through pocket water or anywhere where the drifts are short and the fish are opportunistic.
I was very impressed with how this fly performed. I was blown away how visible it is on the water. I tried a few other dries last night at the river. I tied this on and it hit every time almost instantly. I tied on another fly and ended back with this one as it was the only one bringing success.
