Amplitude Line

Scientific Anglers' premium fly line lineup, available in Textured and Smooth finishes across dozens of species- and technique-specific tapers. All Amplitude lines use the AST Plus slickness additive distributed throughout the coating, which SA reports makes the lines 50% slicker than standard AST. Textured variants add floating and shooting textures to reduce surface tension. Taper options include Infinity, Trout, Streamer, Bass Bug, Bonefish, and others.
