SA Amplitude Textured MPX Floating Fly Line
Built a half-size heavy, the SA 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. 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.
- Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability
- Floating Texture on the tip section for the ultimate in flotation
- Shooting Texture running line delivers longer casts
- The ultimate general presentation line for accurate and consistent casts

FAQ
What makes the AST PLUS slickness additive different from other fly line additives?
The AST PLUS additive enhances shooting performance and increases line durability, allowing for longer casts and better performance over time compared to standard additives.
How does the floating texture on the tip section improve performance?
The floating texture improves flotation, helping the line stay on top of the water and maintain a stable presentation during casting.
Is the MPX line suitable for both still and moving water conditions?
Yes, the MPX line is designed for general presentation use and performs well in both still and moving water environments.

The MPX line casts much farther than my previous model. The floating texture keeps it stable on the surface, and the AST PLUS additive makes it glide smoothly. Great for dry fly presentations in windy conditions.

I noticed a noticeable improvement in casting distance and accuracy. The line feels more balanced and responds well to subtle movements. Slightly heavier than expected, but that’s fine for the presentation focus.
Colin Lyman –
The slickness of the line is impressive. It doesn’t drag or tangle easily, and the tip floats perfectly. I’ve used it in both lakes and rivers, and it performs consistently.
Boris Smith –
Good for general use. The texture helps with float stability, and the added mass in the head gives better control during delicate presentations.
