SA Mastery Series MPX Fly Line

Scientific Anglers


For years, the gold standard in the Scientific Anglers lineup was the GPX taper. From tossing small dries to slinging huge streamers, the GPX could do it all. But all good things must come to an end. 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.


  • Built a half-size heavy to load rods and turn over large flies easily
  • Excellent with dry flies, nymphs, and streamers
  • Features AST slickness additive
  • For use in moderate and cold climates
  • Braided multifilament core
