Monofilament is the usual starting point for general reef fishing. It remains flexible, allows natural bait movement and can be selected in different strengths to suit the ground and expected fish.
As a practical starting point:
• 60lb mono suits general reef fishing over cleaner or moderately broken ground
• 80lb mono provides additional strength and abrasion resistance around reef edges, rubble and mixed structure
• 100lb mono suits heavy coral, larger reef species and situations where fish need to be turned quickly
These are starting points rather than fixed rules. Leader strength should increase as the reef becomes sharper, the fish become larger or the available room to stop them decreases.
Wire serves a different purpose. Its main advantage is protection from species capable of cutting monofilament, including mackerel, sharks and other toothy fish commonly encountered around reef.
Choose mono when:
• Toothy bycatch is unlikely
• Bait movement and flexibility are priorities
• Leader strength can be matched to the reef and expected fish
• Knotted connections or adjustable hook arrangements are required
Choose wire when:
• Mackerel, sharks or other toothy species are likely
• Repeated bite-offs are occurring
• The rig is specifically designed around a coated-wire trace
• Additional protection is required immediately ahead of the hook
Wire is not automatically the best choice simply because the ground is reef.
Leader material should be chosen for the expected contact point—mono for general reef abrasion and wire where teeth create the greater risk.
