The Amplitude Smooth Infinity is designed to be the highest performing smooth fly line available. Made a half-size heavy to load fast-action rods yet suitable for a variety of rod actions, it has the power to cast streamers while retaining delicacy for dry flies. An extended head length mends well, and delivers flies at all distances. The line's versatile general-purpose taper is designed for most freshwater species; an excellent line for trout, grayling, panfish, bass, carp, steelhead, salmon, and pike. For use in moderate and cold climates.
