Quick take

Dacron backing for fly reels that connects fly line to the spool and provides insurance on long runs from large fish.

This 6-weight floating fly line from the Magnitude Smooth Infinity series comes in buckskin and clear, for anglers who want one general-purpose taper for most freshwater species. Its longer head helps with long casts and mending, and it suits streamers, nymphs, dry flies and poppers. The line runs 90 feet in total and is designed for water above 50 degrees Fahrenheit, though it can be fished colder with some hand-stretching.

Best for

  • Fly reels for saltwater species
  • Fly fishing steelhead and salmon
  • Any fly setup targeting powerful fish

Skip if

  • You fish small trout and panfish only
  • Your reel spool is already full with line

Strengths

  • Thin diameter maximizes spool capacity while staying strong
  • High abrasion resistance protects against line breakage
  • Specialty colors improve visibility during spooling and troubleshooting

Trade-offs

  • Dacron has more stretch than modern braided backing
  • Thin diameter makes it harder to grip and hand-strip during emergency situations
  • 250 yards may be excess backing for small trout reels
