Westin W6 ST5 Fluorocarbon 20m 0.92mm 45.1kg Clear

Westin W6 ST5 Fluorocarbon 20m 0.92mm — Maximum Suppleness for Heavy-Duty Leaders

The Westin W6 ST5 (Stiffness Rating 5) Fluorocarbon delivers a rare combination of heavy breaking strain and soft, easy-to-handle material — purpose-built for anglers who demand the best from their leader when targeting large predators in salt or freshwater.

Supple Strength That Ties True

Rated ST5, this line sits at the flexible end of Westin's stiffness spectrum. The exclusive production process yields a compact 0.92mm diameter with 45.1kg breaking strain, yet the material remains soft enough to tie reliable, tight knots without sacrificing tensile strength. Low line memory means fewer tangles and kinks when working with heavier leaders.

Abrasion Resistance Built for Brutal Conditions

Whether you're fishing rocky reef edges, heavy structure, or abrasive-mouthed species, the W6 ST5 Fluorocarbon is engineered to withstand sustained friction. Its fast-sinking property keeps the leader where it belongs — below the surface and close to the fish — while the 100% fluorocarbon construction offers excellent near-invisibility underwater.

Choose the Right Variant

The W6 ST5 Fluorocarbon is available across a wide range of diameters and spool lengths to match your target species and rig requirements. Lighter, longer spools suit finesse and freshwater setups; shorter, heavier spools are tailored to big-game and saltwater applications.
