RIO offers two types of Switch lines; a long head Switch Line, and the short, easy-loading Switch Chucker. Each line has the head and running line seamlessly integrated into each other, which avoids any loop to loop connection running through the guides. The Switch Line is the best choice for anglers that want control of the line and fly at long distance, while the Chucker is best for fishing tight in and for easy casting of big flies, sinking tips and indicator rigs. Built with RIO’s ultra-low stretch ConnectCore Technology.
