When you need big flies for big predator fish such as GT’S, Pike, Musky, Dorado, and Arapaima, the EP®PREDATOR BRUSH is just what you want. This brush is a dense mixture of EP®FIBERS with the addition of EP®THUNDERSTRUCK UV SPARKLE that will push plenty water to attract those predator fish. Remember; the more wraps around the hook the more dense and compact the fly will be.
