Amplitude Smooth Trout Taper Fly Line

Presentation is the name of the game for the Scientific Anglers Amplitude Smooth Trout Taper Fly Line. This floating line was designed specifically with delicately casting dry flies to picky trout in mind. The elongated taper helps land dry flies and small nymphs softly on the water, and the AST Plus slickness additive ensures superior shooting ability and smooth presentations.

Scientific Anglers' Amplitude Smooth series of lines set a new standard for smooth fly line performance. They offer five times less drag and eight times more durability than traditional fly lines, meaning ultra-smooth performance that's built to last.
