About this item

  • Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability
  • Made a half-size heavy to load fast-action rods, but works well with a variety of rod actions
  • Welded Loops
  • Functional in Cold and Medium Temperatures
  • Ideal Dry Flies, Nymphs, Streamers, Poppers/Big Dries, and Indicators


The Amplitude Smooth series of lines are, simply put, the highest-performance smooth fly lines in the world. With up to five times less drag and eight times the durability of traditional lines, this will change the way you look at fly line performance. Built a half-size heavy, the Amplitude Smooth 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.

The short head with a very short front taper casts heavy nymphs and bulky streamers more easily than the other weight-forward lines that SA offers. The line is a half-size heavy like the Infinity series.

Compared to standard fly line this glides through the rod with ease. Making every cast easier and go farther this is definitely worth the price.

The line is decent like the rest of SA's offerings. However, it's texture has added new callouses to my fingers from how much it burns when you are stripping line. Additionally, I've already had parts of it start to deteriorate even though I've only had it for 5 months.
