This is the first fly out of the box if flounder is my quarry. It's also an excellent choice for working drop-offs and guts, or just blind casting to locate the fish.
A simple, yet effective pattern, this fly consists of a chartreuse silicone curl tail, large sparkle chenille body, and a pair of brass dumbbell eyes. I tie them to ride hook up, giving them a semi weedless presentation.

Hook: Sizes #2 & #4
