This fly was designed for fishing in the Marls for bonefish & permit. This fly is also great for redfish, seatrout, snook too! If you&';re fishing freshwater, the large mouth will go crazy over this fly! This is a must have in your fly box. These are tied by Larry Kreh (son of Lefty Kreh) using Lefty&';s materials. Lefty had some of the finest materials in his collection. Can&';t get any better than that! These are tied on size 1/0 hooks.
