DESIGNED FOR THE SPECIFIC DEMANDS of anglers targeting the largest tropical species, these sink tip lines deliver low-stretch, ultra-slick performance in the harshest environments. Engineered specifically for big game saltwater encounters, each line features a powerful front taper designed to cast the largest flies and a short, heavy head to load powerful bluewater rods quickly and efficiently. The design features a 26ft, fast-sinking head seamlessly integrated into an intermediate running line, providing a smooth transition and complete depth control. To withstand extreme conditions, these lines are built with a hard, tropical coating that prevents the line from wilting in the heat, while an ultra-strong core ensures you can successfully battle large fish and resist abrasions from coral and rock structures. Each line incorporates advanced technology to enhance your fishing experience, including a low-stretch core for hard, solid strip sets and a premium coating for maximum slickness and durability. Whether you are fishing deep or targeting fast-moving predators, the density-compensated design ensures your fly stays in the strike zone longer. - Short, heavy head to load powerful saltwater rods - Short, aggressive front taper to cast large flies with ease - Low stretch “DirectCore” for hard, solid strip sets - Built with RIO's exceptionally slick, durable SlickCast coating - Density Compensation for complete depth control - Integrated 26ft sinking head for rapid depth attainment
