RIO’s Leviathan lines have been specifically designed for the largest of tropical species. Each line features a powerful front taper to cast the biggest of flies, and a short, heavy head to load blue water rods. The 250gr Leviathan line is built on a 35lb core, while the 300gr to 400gr lines are built on ocean-tough, strong cores in excess of 50lbs. All Leviathan lines of 500gr and more have ultra-strong cores of 70lbs and more, that will easily battle large fish and resist being cut on coral and rock structures. A hard, tropical coating prevents the line from wilting in the heat.
The 250gr, 300gr, 350gr and 400gr, 26ft Sink tip lines, and the 30 ft, 550gr Billfish Shooting Head have welded loops on both ends for easy rigging. In addition, the Billfish Shooting Head has a bright orange, 4ft long rear section so anglers can easily see the rear end of the head.
