Scientific Anglers Amplitude Smooth MPX Line
Scientific Anglers
The Scientific Anglers Amplitude Smooth MPX fly line featuring the revolutionary AST PLUS slickness additive takes the gold standard for floating fly lines to a new level. The Scientific Anglers Amplitude Smooth MPX series will shoot farther and last longer than any other line on the market. For years, the go-to fly line in the Scientific Anglers lineup was the GPX taper. From tossing small dries to slinging huge streamers, the GPX could do it all. But all good things must come to an end. 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.
- Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability
- An excellent general-presentation line for trout, panfish, bass, grayling and carp; also useful for steelhead, salmon, and pike
