Westin W6 ST5 Fluorocarbon 20m 1.05mm 53.3kg Clear

Westin W6 ST5 Fluorocarbon — Maximum Suppleness for Heavy-Duty Leader Applications

The Westin W6 ST5 (Suppleness Tier 5) Fluorocarbon delivers an unmatched combination of raw breaking strength and soft, flexible handling — purpose-built for anglers who need a heavy leader that still ties clean, strong knots.

Supple Strength Where It Matters Most

Engineered at the ST5 end of Westin's suppleness scale, this fluorocarbon leader material prioritises flexibility over stiffness. The result is a line that handles effortlessly, reduces coiling, and maintains exceptional knot integrity even at the 53.3 kg breaking strain this 1.05 mm diameter spool delivers. Low memory compared to conventional fluorocarbon makes spooling and rigging noticeably more user-friendly.

Incredible Abrasion Resistance, Slim Profile

Westin's exclusive production process achieves a smaller diameter relative to breaking strain, meaning the 1.05 mm profile punches well above its weight in abrasion resistance. Whether you're working rocky seabeds, wreck structures, or toothy species with abrasive mouths, this leader holds up where others wear through. Fast-sinking density keeps rigs fishing at depth without additional weight.
