Scientific Anglers Amplitude MPX WF Floating Fly Line zoom in


Scientific Anglers Amplitude MPX WF Floating Fly Line

The first series of lines to feature the revolutionary AST Plus® slickness additive, the Amplitude series will shoot farther and last longer than other lines. 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.
