New for 2013. Designed to cast large, air resistant and heavy flies with exceptional ease. RIO's Power Fly has been specifically designed to cast large and heavy flies with exceptional ease. The line features a short, powerful front taper that has no problem casting weighted streamers, large terrestrial patterns and nymph and indicator rigs. The line is heavier than the industry standard to load modern rods with ease, and is built with a supple, coldwater coating that features RIO's XS and AgentX technologies for the very best in performance.
