Prepare to experience the highest-performance smooth fly lines in the world with the Scientific Angler Amplitude Smooth Infinity series. Enjoy up to five times less drag and an impressive eight times more durability than traditional lines, revolutionizing the way you perceive fly line performance.

Traditionally, fly fishing wisdom suggests that there's no "do it all" freshwater line. But we beg to differ. The Amplitude Smooth Infinity possesses the power to cast streamers with precision while maintaining delicacy for dry flies. It excels at mending, and its performance is unparalleled at any distance. With a half-size heavier design, extended head length, and substantial front taper, this line is perfect for a wide range of freshwater species, from trout and panfish to pike and steelhead.

There's a reason we named it the Infinity: the possibilities with this line are endless.
