Rio's new Avid Series of lines were developed for the avid fly fisher with tapers and technology that enhance the fly fishing experience. Avid lines are built with an ultra slick, dirt-repelling coating over a supple core that features AgentX Technology for buoyancy and smoothness and feature a neat welded loop in the front end for fast, easy rigging.Read more
We've all wanted a higher floating line for a long time but, even as remarkable as our fly lines are, they can't float without a little technological intervention. Traditionally, getting a line to float has required mixing a bunch of tiny glass balls (called microspheres) into the soupy coating compound prior to the curing phase. The higher you want your line to float, the more glass balls you must add. But this creates a problem in that the microspheres can create a rougher, microscopically abrasive coating that has less plastisol which results in a structurally weaker fly line that cracks.
So, after years of experimenting with exotic compounds and plenty of waist-deep R and D, our lab people discovered an element far more buoyant than the rest of the industry. But the right element was just the start. It took an exponential leap in rethinking the manufacturing process to put it all together. AgentX is a result of the combination of a highly buoyant undercoat coupled with a super-smooth outer coating, and it produces the smoothest, most durable, and highest floating fly lines imaginable.
