Scientific Anglers Amplitude Smooth Trout GP is a line similar to the Infinity, but with slightly extended tapers and a slightly lower total weight. This makes the line an excellent choice for lighter general-purpose trout and grayling fishing when heavier flies or indicator rigs are not required. The line's long rear taper makes line control easy during the drift.

The Amplitude Smooth series of lines are, simply put, the highest-performance smooth fly lines in the world. With up to five times less drag and eight times the durability of traditional lines, this will change the way you look at fly line performance.
