RIO's Mainstream series of fly lines have been developed to meet the overall needs of the average and novice fly fisher, and are designed to optimize rod performance with slightly heavier and shorter head lengths. Every Mainstream line undergoes the same rigorous production processes and quality control standards as all RIO fly lines, and is made in RIO's Idaho manufacturing facility. Each line is built with a slick coating on a supple memory-free core, for the best in performance.
RIO's newest leaders are the strongest trout leaders ever made, with tensile strengths up to 20% more than regular leaders. A technical modification of the nylon copolymer formulation has resulted in prodigious strength increase, without compromising the knot strength or suppleness. Simply put, these are the strongest, most reliable trout leaders ever made. Each pack contains 2 premium leaders.View full product details
