Quick take

A 20 lb braided Dacron backing with tight round braid that minimizes twist and knots perfectly.

This pink Micron backing is a 100-yard spool of 12-carrier round braid made from Dacron, with a 20 lb line test. It fills a fly reel behind the fly line and suits most freshwater species and smaller saltwater fish. Anglers who want a tight, round braid in a bright color for tracking it on the reel can pick this 20 lb size.

Best for

  • Freshwater trout and bass fly fishing
  • Smaller saltwater species like school stripers and redfish
  • Anglers who need reliable, tangle-free backing

Skip if

  • You target very large saltwater species; 30 lb is better
  • You need extremely thin diameter for tight wrapping

Strengths

  • Tight round braid eliminates twist compared to flat braids
  • Smooth low-friction finish eases line passing through guides
  • 12-carrier construction ensures superior strength and reliability

Trade-offs

  • Dacron has some stretch; less direct connection than modern braids
  • Zero twist design means it will still twist if improperly used
  • Pink color is visible but may not suit all anglers
