Overview
Sufix's 604-106 spool holds 330 yards of clear nylon monofilament in 6 lb test, sized for light spinning reels rather than heavier saltwater setups.
Monofilament stretches more than fluorocarbon or braid, which helps absorb sudden strikes on light line, and the clear color keeps it less visible in clear water. At 6 lb test, it sits toward the lighter end of the mono range.
