Leader & main line

Japanese sizing throughout: PE size for the main line, fluorocarbon size for the leader (#1 ≈ 4 lb). Tap your PE and the water; read the leader range and the length range.

• Every PE size takes a RANGE of leaders — PE 0.8 fishes 6–10 lb: the thin end for pressured, clear-water finesse, the thick end around cover
• Below PE 1.0 there is no cover option: the main line itself is too fine for grass and rock. From PE 1.0 to 1.5, cover means a LONGER leader (2–3 m) so the abrasion-resistant part reaches the rock
• Thin plus very long dulls the bait's action — but a 3 m, 1.5-size leader is exactly what beats heavily pressured fish; accept the trade
• A long leader means the knot goes through the guides on every cast; that is where casts fail. Keep it to a rod length unless you have a reason, and use an FG
• Heavy PE with a leader: avoid rods with many small guides — the knot hammering through micro guides damages the guide inserts and the blank
• A short leader (under 1 m) belongs on a small ball-bearing swivel: it tames twist and removes the knot from the cast altogether
• PE 2.5–3.0: only a 30–40 cm bite leader for glide baits and big swimbaits; PE 3.0 and up goes straight to the bait
• Soft fluorocarbon for finesse (action), stiff fluorocarbon for cover (abrasion, less wrapping around the hook)
• Run your fingers down the leader after every fish and every rock; a nick you can feel is a leader you retie
• Clear water: add 30–50 cm. Stained water: take 30–50 cm off — the leader is doing less stealth work and a shorter one casts better
