    There’s a sipper 40 feet away and he looks like he’s eating tricos. The natural rhythms of the rise and the river begin to make sense, so you ready yourself to cast. In that moment, you shouldn’t be thinking about your fly line, because you should trust it implicitly. In that moment, you need the Amplitude Smooth Trout taper. Featuring our unparalleled AST Plus slickness additive, the Amplitude Smooth Trout is designed specifically for precise presentations and those who love dry flies. 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.

    • Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability
    • Excels in medium-to-long distances with dry flies and smaller nymphs; wonderful on glass and bamboo
    • The best smooth, true-to-grain-weight line for casting small dry flies to picky risers
    • Designed specifically for chasing trout; also useful for grayling and panfish
    • Elongated front taper is designed for delicate presentations
    • For use in moderate and cold climates
    • Braided multifilament core

    The best fly line does cost a little more, but there's a reason for that. SA's trout line is perfect for any novice, intermediate, or advanced fly fisherman!

    Scientific Anglers Amplitude Smooth Trout, a must have fly line, you will have an incredible experience fishing small and large trout. Like all Scientific Anglers lines, this is a 100% recommended wonder. You will enjoy it to the fullest. A great line, I use it with a Redington Crux rod they are a wonderful pair.

    Just so slick
    CHess (Idaho) | May 10th, 2021
    The long even taper and the incredible slickness of this line make it perfect for light rods and small flies in demanding conditions. It's effortless to get this line moving, and my ability to turn flies over and land them right where I want to has improved 2x.

    Put on a slower action 3wt used mainly for small creeks or throwing dries. Performs great, and a much needed improvement over the all purpose half heavy line i had previously. Would highly recommend
