I can simply tell you that year after year these patterns have proven to be very effective with just about anything that swims! The reason is simple - they represent exactly what a predator fish is looking for. All my flies are designed to be the closest imitation of the baitfish, so the best way to fish them is with slow strips and short twitches. You'll catch Tarpon, Snook, Striper, Bluefish, Weakfish, Sea Trout, Redfish, Jack Crevalle, Tuna, Bonito, False Albacore, Sailfish - you name it. The Peanut Butter Black/Purple is still my number one seller, especially for Tarpon. It has fooled them everywhere. Everybody is talking about it!
