Product details

The Scientific Anglers Amplitude Smooth Infinity Fly Line is designed for freshwater fly fishermen and is considered a high-performance, smooth fly line. With up to five times less drag and eight times the durability of traditional lines, this line has the power to cast large streamers, but maintain the finesse for dry fly presentations. Key Features:

  • Braided Multifilament Core – The core material of the fly line will help with overall line strength and reduce line tangles.
  • Heavier Than AFFTA Standard Weight – The actual line weight is designed to be slightly heavier than standard weight to more easily load modern, fast-action fly rods.
  • General Purpose Taper – The taper is designed to make this a versatile fly line with applications for most freshwater fishing.

Just about everything! This line is coated with a low-friction, high-float treatment providing easier casting at distance and more line speed! Super durable also.

This in my opinion is the best all around line on the market, winning a ton of awards in the past two years! This line is durable and really performs in all conditions. This line has what's called a camo tip in the final ten feet of line, allowing you to gauge distance with ease. Really well designed taper. It performs in all water types, it's extremely durable, and the new AST plus has your line smooth as butter. It outlasts any other line that I have had the chance to test!
