Rio Avid Grand Fly LineRio's Avid Grand is designed with technology to enhance the fly fishing experience, with ultra-slick performance. Floating lines in the Avid series come in RIO’s two most popular and proven tapers, the Gold and the Grand. The Avid Gold is ideal for the angler who prefers smaller flies and more delicate presentations while the Avid Grand is better suited to anyone fishing larger flies where powerful turnover is more important. Both lines are built with RIO’s SlickCast technology for unmatched slickness and durability.
