RIO Products Premier Rio Gold Fly Line WF3F Moss/Gold. The line has a long head and back taper that give casters total line control and stability at range - whether casting or mending. The unique profile is designed to load a fly rod at close range and has a front taper that delivers perfect presentation of flies between sizes #22 and #2. RIO has enhanced the performance of this wonderful trout line by building it with SlickCast - RIO's proprietary coating technology. SlickCast creates the slickest most durable fly lines on the market. Lab tests show that lines built with SlickCast have the least amount of friction ever measured in a fly line. In addition the line features MaxFloat Tip Technology RIO's proprietary tip coating formula that floats more than twice as high as regular line tips without any increase in diameter. The RIO Gold is the ultimate all round floating line for the trout fly fisher.
