Quick take

A low-memory fluorocarbon blend line that balances near-invisibility with dialed stretch for better hooksets on moving baits.

Sold as a 550-yard spool of 10 lb clear line, this is a fluorocarbon blend rather than pure fluorocarbon, keeping fluoro's low stretch and slim diameter with less stiffness and memory. The 10 lb test suits jerkbaits, cranks and chatterbaits, and it works on both spinning and casting reels. The large spool suits anglers who go through line quickly and want a reel kept stocked.

Best for

  • Jerkbaits, crankbaits, and chatterbaits
  • Swimbaits and jigs in cover

Skip if

  • You need 100% fluorocarbon for pure bottom contact
  • You fish exclusively topwater

Strengths

  • Low memory means fewer tangles on spinning or casting reels
  • Measured diameter ensures consistent abrasion resistance

Trade-offs

  • Not 100% fluorocarbon; some visibility in clear water
  • Fluorocarbon blend is still less stretchy than monofilament
  • Frequent re-spoolers need to manage multiple spool sizes
