Rio Elite Flats Pro StealthTip, the BEST Flats Line on the market—perfect for bones, perms and poons with low-stretch, SlickCast performance! Conquer the flats with RIO’s Elite Flats Pro tropical saltwater line. This line has a mid length head and long back taper for smooth, effortless loops, and a weight distribution that provides perfect presentations of just about any fly you are likely to use. 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 the line is built with SlickCast—the slickest, most durable coating on the market.
