We tested RioMax Plus on the Deschutes, while fishing for steelhead. We had no failures. RioMax Plus is designed to compete in the salmon/steelhead arena where Maxima has reigned supreme for 30-years. RioMax Plus is an incredibly tough, medium stiff tippet material, designed to be the most abrasion resistant nylon leader material available. It is perfect for fishing streamers for trout, and for salmon, steelhead, bass and for saltwater species such as bonefish and striped bass. A slick coating makes it very easy to tie knots.
