The One Line to Rule Them All—With Bite.
The SA Amplitude Textured Infinity is the ultimate do-everything trout line for anglers who demand power, finesse, and unmatched durability. With a half-size heavy taper and extended rear section, it loads modern rods quickly while still offering superior loop control, roll casting ability, and delicate presentations.
What makes this version shine is the textured AST Plus coating—it’s slicker than any smooth line on the market and lasts significantly longer. The micro-texture reduces friction for longer casts, improves floatation, and sheds water for cleaner pickups—all while making a signature “zip” sound you’ll either love or fear.

This line performs exceptionally well in both still and moving water. The textured coating makes a noticeable difference in cast length and water shedding. I’ve used it for both dry flies and nymphs and it handles the loop control perfectly.

The zip sound is unique and immediately recognizable. I love how it casts smoothly and stays dry even in light rain. It’s become my go-to for trout fishing in the mountains.
Isaac Vaughan –
Great durability and feel. The texture helps with floatation and keeps the line clean after a few casts. A bit more expensive, but worth it for the performance.

I’ve switched from a smooth line to this textured version and noticed a clear improvement in roll casting and sensitivity. The loop control is excellent for delicate presentations.
