Scientific Anglers – Amplitude MPX Textured Fly Line | Power meets finesse in the ultimate presentation line.

The Scientific Anglers Amplitude MPX Textured Fly Line blends power and precision for versatile freshwater performance. Featuring the groundbreaking AST Plus slickness additive, this line shoots farther, mends cleaner, and lasts up to eight times longer than conventional lines. Its triple-textured surface reduces friction, helping anglers achieve smoother loops and longer casts without compromising control.

Built a half-size heavy and with a more forward-biased taper than its predecessor, the GPX, the Amplitude MPX is optimized for modern fast-action rods. It loads quickly and delivers larger flies with authority, yet maintains the finesse needed for delicate dry fly presentations. Whether you’re tossing terrestrials, nymphs, or streamers, the Amplitude MPX is engineered to be your go-to fly line for all-around trout fishing.
