Rio's Selective Trout II lines cast easily and make delicate presentations easy. Unique tapers created specifically for technical trout fishing and selective trout in all weather conditions. Memory free in winter due to its ultra supple coating and braided multifilament core. The tip floats extremely high due to Rio's proprietary SFT- Super Floatation Technology- manufacturing process, while the entire line is made with Rio's patent pending AgentX undercoat that ensures a high floating and super smooth line. Rio's new XS Technology produeces an extraordinarily slick, dirt-repelling coating that keeps the line clean and results in far reaching casts. Rio has included a welded loop on the front end of the weight foward line to facilitate changing leaders, which can be cut off without compromising the taper.
