Rio Mainstream #9 Weight Forward Floating Saltwater Fly Line

Targeted to the overall needs of the average fly fisher.

    RIO's Mainstream saltwater 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 saltwater line is built with a hard, saltwater coating for the best in performance.

Designed to optimize rod performance at normal casting ranges.

An all-purpose saltwater line ideally suited for fly fishers fishing in temperate-to-tropical conditions for multiple species. The line features a hard tropical coating that will not soften in the heat. Based on the RIO Clouser taper that will turn over big flies in the wind.
