RIO's Elite GT (Giant Trevally) line has been specifically designed for the demanding conditions faced by the hardcore GT angler. Each line is built on RIO's low-memory DirectCore that is extremely easy to anneal (stretch) and lies perfectly straight on the water, yet retains the stiffness needed to cast in hot conditions. In addition, this line is built with SlickCast, creating the slickest, most durable coating on the market""producing the least amount of friction ever measured in a fly line.
