Sci Angler Amplitude Smooth Trout Floating Fly Line
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.
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.

This line feels incredibly smooth and casts with ease. I’ve been using it for dry fly fishing in riffles and it consistently delivers accurate, clean casts. The drag reduction is noticeable, especially when targeting small trout in fast water.

After switching from a traditional line, I noticed a big difference in how the fly moves through the air. The AST Plus additive makes it glide naturally, and I can now present dry flies with more confidence.

Great for precise casting. The line holds up well in wet conditions and doesn’t tangle easily. A bit more expensive, but the performance justifies the cost for serious dry fly anglers.
