variants available — selected variant links direct to its Amazon page.
The RIO Mainstream Striper is a clear intermediate sinking fly line designed specifically for saltwater striped bass fishing, though its powerful weight-forward taper and sinking configuration make it equally effective for Great Lakes steelhead and salmon. The clear intermediate sink rate excels when fish are holding in mid-water columns or when subsurface presentations are needed without going full-sink.
