The first series of lines to feature the revolutionary AST PLUS slickness additive, the Amplitude series from Scientific Anglers 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.

I usually use Infinity lines. I wanted to get a slightly different feel on an Echo 6 weight, TFO Blue Ribbon 3 weight, and Redington Trailblazer 5 weight. This line was the perfect solution for me! It changes the fast action rod to feel slightly more like a medium fast, with a little more bend and more sensation on the loading action on the rods. Definitely a great line!
