RIO's OutBound Custom fly line is built with a 35ft long, level, fast-sinking head that is designed to be cut and tuned to individual casting and rod preferences. The powerful head is the perfect choice for angler's casting large flies who want fast depth and maximum casting distance. In addition, the fly line is built with SlickCast—the slickest, most durable coating on the market.  The T-14 works best on rods between #10 and 12wt – depending on how much is cut off. SlickCast SlickCast creates the slickest, most durable coating on the market – producing the least amount of friction ever measured on a fly line. Features: DualTone Marks the sweet spot of a fly line by providing an obvious color change in the line at the sweet spot.
