Winston Trout Energy Fly Line Size:WF4F and loop stability expected fromSmooth Casting Trout Fly Line. Winston ENERGY fly lines was designed to enhances the energy transfer between the rod and line. Winston carefully measured the dynamic characteristics of fly rods at various flex points, then applied an engineered system to precisely design lines that are ideal for each rod weight. The result is a series of lines that perfectly match the performance characteristics of modern fly rods. Expect this line to cast and fish
