The RIO Grand is perfect for long distance casting on large rivers and open lakes. The RIO Grand is a state-of-the-art in fly line technology with distinctive benefits for the trout fly fisher. The Rio Grand is one half line size heavier than AFTMA standard and features more weight distributed toward the front of the line to easily load fast action fly rods. The tip floats extremely high due to RIO's proprietary manufacturing process, yet gives a smooth light delivery of even the smallest dry fly. The weight forward taper features a slightly heavier load to activate the faster modern fly rod, yet the rear taper is long enough for roll casting. The line is the product of RIO's SlickShooter Process and incorporates a supple coldwater, super slick, self-lubricating, dirt-resistant coating on a nylon multifilament core. This is the perfect line for wet or dry fly fishing. RIO has included a welded loop on front of the fly line to facilitate changing leaders and increase floatabillity. In all our tests we have found excellent turnover and presentation with this loop. When landing fish, it slides through the rod guides more easily than the customary nail knot. Traditionalists can cut this loop off and not compromise the taper. 100' long.
