The Rio Grand fly line is designed to load fast action fly rods more quickly and with less line out than regular lines. The Rio Grand is roughly one line size heavier than standard fly lines and that extra weight makes the Rio Grand an excellent all-purpose line that is capable of casting larger nymphs and streamers or punching casts into the wind. In addition, the Rio Grand utilizes some of Rio's best technologies such as their Agent X technology for maximum durability and slickness, their MaxCast technology for impressive flotation and dirt repellency, and also included is their MaxFloat Tip technology for an even higher floating tip. Includes a welded loop on the front and back ends of the line for easily attaching to your backing and adding/removing leaders. Total line length is 80 feet for 3wt, 90 feet for 4wt and 5wt, and 100 feet for 6wt and above.
