This fluorocarbon is ideal for tying discreet, dense, and abrasion-resistant leaders. Its transparent color reduces visibility underwater, which is useful when fish take a long time to bite or refuse rigs that are too conspicuous. Lower breaking strengths are suitable for thinner leaders, while higher breaking strengths are designed for heavy fishing and fish capable of wearing down the rig. The choice is made by considering the diameter, breaking strength in pounds, and the expected abrasion level in the fishing area. The 20m spool is suitable for ready-to-cut rigs and regular replacements.
