Scientific Anglers Amplitude Smooth Infinity Fly Line

  • Sale
  • Regular price $99.99


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.

The conventional wisdom in fly fishing is that there’s no such thing as a “do it all” freshwater line. We have something to say about that. The Amplitude Smooth Infinity has the power to bomb out streamers, yet retains delicacy for dry flies. It mends like an absolute dream, and delivers flies at all distances. Built a half-size heavy, with a long head and substantial front taper, it’s perfect for everything from trout and panfish to pike and steelhead. There’s a reason we call it the Infinity: there is no end to what you’ll be able to do with it.

  • Features the revolutionary AST Plus slickness additive for superior shooting ability and increased durability
  • Extremely versatile general-purpose taper designed for most freshwater species; an excellent fly line for trout, grayling, panfish, bass, carp, steelhead, salmon, and pike
  • Made a half-size heavy to load fast-action rods, but works well with a variety of rod actions
  • Extended head length for long-distance casts and superior mending ability
  • Excellent for dry flies, nymphs, and streamers
  • Available in two color schemes: standard and camo; the camo scheme features a mottled front taper for increased stealth
  • For use in moderate and cold climates
  • Braided multifilament core

If you already use Rio Gold but you would like a more durable option, try one of the new Infinity Lines. Some of our personal rods have been the testers, and for all around trout use it doesn't get much better. If you prefer non textured lines, then go with the smooth. If you want a textured line, check out the other Amplitude version of this taper.
