Scientific Anglers Amplitude Textured MPX
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.

FAQ
What makes the AST PLUS additive different from other slickness additives?
The AST PLUS additive is specifically engineered to improve shooting distance and line durability, offering a more consistent and longer-lasting performance compared to standard additives.
How does the floating texture on the tip improve fishing performance?
The floating texture enhances buoyancy, allowing the line to stay on top of the water longer, which improves visibility and presentation when casting.
Is the MPX line suitable for both freshwater and saltwater use?

The MPX line performs exceptionally well in casting. It shoots farther than my previous line and stays on the surface longer, which helps with visibility. The texture feels smooth and the line holds up well after several uses.

I noticed a noticeable improvement in how the line behaves in the water. The floating tip helps with presentation, especially in light wind conditions. It’s a bit heavier than the GPX, but the added mass gives better control.

The AST PLUS additive makes a real difference. I’ve used it in multiple fishing scenarios and it consistently performs better in terms of distance and durability. Highly recommend for anglers who value precision and performance.
