Field Notes

Fly line backing is used on the reel arbor under fly line to increase total line capacity and provide extra reserve for long runs. It is especially useful when targeting strong fish that may take drag and strip line. The gel-spun material is thin for its strength, helping maximize spool capacity.

Pros

  • Very high strength for its diameter
  • Thin profile increases reel capacity
  • Designed specifically as fly line backing

Cons

  • Not a standalone fishing line
  • Requires proper knotting and reel setup
