Each line is built on RIO’s low-memory DirectCore that is extremely easy to anneal (stretch) and lies perfectly straight on the water, yet retains the stiffness needed to cast in hot conditions. Each line has a short, quick loading head that will easily cast and turnover typical large flies, and a range of density options ensures anglers are covered for all species, conditions and waters.
