A double taper line designed for slower action rods - especially bamboo, glass and “classic” action graphite rods, with ultra-slick performance

LightLine Double Taper


RIO’s LightLine double taper has been designed to load slower, more traditional action fly rods such as bamboo, glass and the more “Classic” flexing graphite rods. Built to precisely match the industry line standards, this line will not overload such rods – even at longer range. The weight distribution and short front taper ensures the line loads at close range, making it ideal for fishing on smaller creeks and streams, while the softer, supple coating ensures the line remains relaxed and easy to handle in the majority of conditions. In addition the line is built with SlickCast—the slickest, most durable coating on the market. 

Note: There are no welded loops, no EasyID and no MaxFloat tip on sizes 000,00 & 0

SlickCast creates the slickest, most durable coating on the market – producing the least amount of friction ever measured on a fly line.

MaxFloat Tip technology is a high float coating that floats more than twice as high as regular fly line tips, without any increase in diameter



Marks the sweet spot of a fly line by providing an obvious color change in the line at the sweet spot.
