Quick take

A five-weight floating fly line with AST Plus coating that shoots smoothly for medium and long-distance dry fly and nymph presentations.

The Scientific Anglers Amplitude Trout fly line is a 5-weight floating weight-forward taper for anglers who fish dry flies, small nymphs and streamers at medium to long distances. Its floating tip section helps keep the front of the line on the surface, and the shooting-texture running line is made to carry long casts. The head runs about 68 feet, which suits anglers working a 5-weight rod on trout streams and lakes.

Best for

  • Trout rivers and streams in medium to long casting situations
  • Dry fly and small nymph presentations
  • Smooth shooting for delicate deliveries

Skip if

  • You fish short-range tight cover
  • You need a fast-sinking line for deep nymphs

Strengths

  • AST Plus coating shoots farther than standard fly lines
  • Textured shooting line reduces tangles and hesitation
  • Moss color is visible without spooking fish

Trade-offs

  • Five-weight is too light for salt water or large streamers
  • Coating wears with use; replacement line needed eventually
  • Smooth casting takes practice to master
