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. There are two sizes available, one built with a T-11 fast sinking head, and one with a T-14 extra-fast sinking head. The T-11 works best on rods of 8wt to 10wt in size, and the T-14 on rods between #10 and 12wt – depending on how much is cut off.
