MPX Mastery Presentation Taper Amplitude Fly Line

Being able to cast a hundred feet out may look sweet, but how many fish have you actually landed from that far out? Being a more refined version of the super-powerful GPX taper, the Scientific Anglers MPX Mastery Presentation Taper Amplitude Fly Line quickly loads modern fast-action fly lines while maintaining the ability to make more delicate casts when you're confronted with a short-distance casting scenario. And since a line that casts like a dream but immediately sinks once it hits the water is basically worthless, Scientific Anglers finished the line off with its AST Plus slickness additive and added an extra floating texture on the tip to keep your line (and fly) riding high on the surface.


  • An all-purpose line for casting nymphs, large dries, and streamers
  • Refined MPX taper strikes a balance between power and precision
  • Weighted a half-size heavier to load fast-action rods
  • AST Plus slickness additive smoothly shoots through guides
  • Floating texture on tip section keeps line floating high
  • Item #SAS002H
