Liquid S has larger diameters, larger arbors and increased strength-to-weight ratios that come from the unique pocket spar frame and spool design. The arbor shape has been redesigned for cleaner spooling, and the drag knob is now larger, and if we can say it, "gripier". Liquid S carries the Liquid name to a higher level.
