SA Amplitude MPX


HEADHUNTERS SAYS: For $129 you can get a pretty good fly rod. And you can get a great fly line. The new Scientific Anglers Amplitude is the slickest shooting line you will ever cast. But if you’re an advanced caster who fishes in situations where maximum distance and speed are required, you will love this line. SA rates this line as a 1/2 line size heavy, but in todays world of underrated line weights, this almost feels like a standard sized line. The textured coating adds distance to everyone who casts it for the first time. The MPX has become the most popular general purpose Fly Line in our shop.


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.

Built a half-size heavy, the MPX taper starts where the GPX left off. Redesigned with more mass toward the front of the head, the MPX provides the same benefits of the GPX, with an added emphasis on presentation. The power is still there, only with an added bit of finesse. Meet your new best friend.
