Features 5

  • Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability
  • An excellent general-presentation line for trout, panfish, bass, grayling and carp; also useful for steelhead, salmon, and pike
  • Made a half-size heavy to load fast-action rods, but works well with a variety of rod actions
  • Best for large dry flies, nymphs, and streamers

Description

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.

A good line for a streaner and bead-head fly fisher
Color: Optic Green / Moss / Buckskin Size: 4 wt.
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.

Smooth like butter
Color: Optic Green / Moss / Buckskin Size: 5 wt.
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.

Not as described
Color: Optic Green / Moss / Buckskin Size: 5 wt.
Smooth so far, but the back end of fly line was not welded as the description and the box stated makes me worry that this is not the correct product.

Texture and Durability Issues
Color: Optic Green / Moss / Buckskin Size: 5 wt.
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.
