Westin W6 ST5 Fluorocarbon 20m 1.2mm 62kg Clear

Westin W6 ST5 Fluorocarbon 20m 1.2mm 62kg — Maximum Suppleness for Heavy-Duty Leaders

The Westin W6 ST5 (Suppleness Tier 5) Fluorocarbon delivers an exceptional combination of raw strength and soft, flexible handling in a 1.2mm diameter leader rated to 62kg — built for anglers who refuse to compromise on knot strength or durability in demanding conditions.

Soft, Supple Construction That Ties Tight Knots

Westin's exclusive production process engineers this 100% fluorocarbon leader to be extremely soft and supple at the ST5 end of the suppleness spectrum. Low line memory makes it easy to straighten and manage on the bank, while the supple nature of the material allows knots to seat cleanly and hold tight under load — crucial when fishing with heavy breaking strains.

Incredible Abrasion Resistance and Fast Sinking

Despite its smaller-than-expected diameter for a 62kg leader, the W6 ST5 delivers incredible abrasion resistance that stands up to rough structure, rocky bottoms, and the abrasive mouths of large predators. The fast-sinking fluorocarbon material gets your rig down quickly and stays virtually invisible in the water column thanks to its refractive index close to water.

Choose the Right Variant

The W6 ST5 Fluorocarbon range spans a wide variety of diameters, breaking strains, and spool lengths to cover everything from finesse freshwater fishing to the heaviest saltwater and big-fish applications.
