Designed for the needs of the beginner and novice fly anglers The RIO Mainstream Trout fly line is built with slightly heavier and shorter head lengths, this helps beginner anglers learn how to feel when the line is loaded up and ready to cast, as well as optimizes the angler’s rod performance. The RIO Mainstream Trout fly line is built with a slick coating on a supple memory-free core, and undergoes the same rigorous production processes and quality control standards as all RIO fly lines.
