Skagit casting requires a line with a very short, 25-27 ft (7. -8.3 m), heavy head that propels heavy sink tips & big flies great distances with a very short casting stroke. Skagit casting is easy for novice or experienced casters to learn. When casting Skagit lines the total head length should be matched to the rod; the total head length including the sink tip should be no more than 3 3 times the length of the rod. To adjust for rod length & loading simply add a Skagit Cheater to achieve the desired load & length. RIO's Skagit lines have a revolutionary design that is perfect for Skagit casting. Available either as a body only, to which you attach one of RIOs 15 ft tips, T-8, T-11 or T-14 (sold seperately), or as a Versi Tip model that comes packaged with a shooting head wallet, a 5 ft cheater & a 15 ft DC Type (ips, 15 cm/s) & a DC Type 8 (8 ips, 20 cm/s) sinking tip. The line is yellow with a black loading point for optimum casting control.
