Amplitude Smooth Anadro Taper Fly Line

Designed for nymphing in slow-moving streams and large open lakes, the Scientific Anglers Amplitude Smooth Anadro Taper Fly Line is one of the highest-performing smooth lines on the market. It has improved durability and reduced drag compared to traditional smooth lines—in part thanks to the AST Plus additive that ensures better performance on the water. The Amplitude features a weight-forward design which helps load your rod, and an extended rear taper that makes mending and controlling the line easier, even with indicator, double, and dropper fly rigs. Scientific Anglers recommends purchasing the line weight that corresponds with your rod, as the Amplitude is already overweighted by 1.5 sizes to help turn over large, air-resistant flies.
