Scientific Anglers Amplitude Smooth Infinity

Versatile, all-around, 1/2 size heavy, extended head fly line
Price: $99.95
Product Details

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.

Scientific Angler Amplitude Smooth Infinity comes in 4 color options:
  • Optic - Optic Green / Mist Green / Buckskin
  • Camo - Bamboo / Buckskin / Camo
  • Glow - Optic Green / Mist Green / Glow Nighttime - Ivory Daytime (Shop Glow)
  • Orange - Optic Green / Satin Orange / Creamsicle
Features
  • Evolutionary AST Plus slickness additive for superior shooting ability and increased durability
  • Extremely versatile general-purpose taper designed for most freshwater species; an excellent 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
  • SA AMP SMTH INFNTY WF X F (X = line weight)

Review: SA knows how to build a fly line. Infinity cast more like a traditional line of the past but it does it without the friction of the past. This line slides through rod guides as if they are not there. The taper really lets one aerialize line for precision casting. I really enjoy casting it
