Scientific Anglers Amplitude Textured Infinity Fly Line
THE GO-TO LINE FOR ALL FRESHWATER SPECIES
The first series of lines to feature the revolutionary AST PLUS slickness additive, the Amplitude series will shoot farther and last longer than any other line on the market. It’s slickness down to a science.
Description
A textured line will help you do a number of things better. Your line will shoot through the guides with substantially less friction, allowing you to maximize your distance. The hex-shaped texture in the head section keeps the line floating higher in the water than any fly line has before. On top of all this, the infinity taper now comes in the textured Amplitude series. This may be the best all-purpose trout line we’ve ever seen!

FAQ
What makes the Amplitude line different from other fly lines?
The Amplitude line features a hex-shaped texture in the head section that reduces friction and keeps the line floating higher in the water. It also includes the AST PLUS slickness additive, which improves casting distance and durability.
Is this line suitable for trout fishing?
Yes, the Amplitude Textured Infinity Fly Line is specifically designed as a go-to line for all freshwater species, including trout.
Does the textured surface affect line sensitivity?
The textured surface reduces friction during casting, which can improve distance and line performance, but does not significantly alter sensitivity in typical use.

I’ve used several fly lines over the years and this one stands out. The casting distance is noticeably better, and the line floats higher in the water. It’s reliable for both dry fly and nymphing in streams.
Zoe Paterson –
The texture helps the line glide through the guides smoothly. I’ve noticed less line drag and better control when casting in windy conditions. Great for all-around use.
Tim Gray –
Solid performance in cold water streams. The floating action is excellent, and the line holds up well after repeated use. A bit more expensive, but worth it for the quality.

This line has improved my casting accuracy and consistency. The AST PLUS additive makes a noticeable difference in how it performs through the guides.
