Quick take

A versatile weight-forward fly line for trout and panfish, built half-size heavy to load fast-action rods.

This camo Amplitude Smooth Infinity in WF-3-F is a freshwater fly line for trout, panfish and bass. Its half-size-heavy profile, long head and substantial front taper suit anglers who want one line for dry flies, nymphs and streamers. The WF-3-F size carries about 110 grains in its first 30 feet, and the AST Plus slickness additive is built in to help it shoot smoothly.

Best for

  • Dry fly and nymph fishing for trout
  • Panfish and pike on moving water
  • Anglers using fast-action rod blanks

Skip if

  • You want a specialized sink-tip line
  • You fish exclusively slow-action rods

Strengths

  • Extended head length helps long-distance casting
  • AST Plus coating reduces drag for cleaner casts
  • Half-size heavy loads fast-action blanks efficiently

Trade-offs

  • Weight-forward design trades delicacy for distance
  • General-purpose line works less precisely than specialized ones
  • PVC coating can stiffen in very cold water
