The Premier RIO Gold has a revolutionary taper design that gives incredible loop stability at distance, a unique profile that allows a rod to load at close range and a front taper that delivers perfect presentation of flies between sizes #22 and #2. The RIO Gold is the ultimate all round, floating line for the trout fly fisher and is built with '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. In addition, this line is built with SlickCast, creating the slickest, most durable coating on the market, producing the least amount of friction ever measured in a fly line.
