Westin W6 ST3 Fluorocarbon 0.343mm 35m 7.9kg Clear

Westin W6 ST3 Fluorocarbon — Invisible, Hard-Hitting Leader Material

The Westin W6 ST3 Fluorocarbon (ST = Suppleness Tuning) in 0.343mm / 7.9kg delivers a precision-balanced blend of sensitivity, impact strength, and near-invisibility — purpose-built for anglers who demand more from their leader material.

Low Visibility Where It Counts

Fluorocarbon's lower refractive index means this clear line bends light far less than comparable monofilament, making it significantly harder for fish to detect underwater. At 0.343mm, it sits in the sweet spot for medium-duty leaders where a stealthy presentation can be the difference between a take and a refusal.

Fast-Sinking, Strong, and Abrasion-Ready

The ST3 medium stiffness rating strikes a practical balance: enough rigidity for reliable hook-setting and controlled presentation, while retaining sufficient knot strength for demanding conditions. The fast-sinking profile gets the bait or lure into the strike zone quickly, and exceptional abrasion resistance holds up against rocks, gravel, mussel beds, and toothy fish alike.

Choose the Right Variant

The W6 ST3 Fluorocarbon is available across a wide diameter range — from ultra-fine to heavy-duty — each matched to specific applications, species, and setups.

• 50m / 0.14mm / 1.4kg — ultra-light finesse fishing, small stream trout, micro-lure leaders

• 50m / 0.17mm / 1.7kg — light drop-shot or nymph leaders, clear-water perch and roach

• 50m / 0.19mm / 2.2kg — refined presentation leaders, small predators in pressured waters

• 50m / 0.219mm / 3.4kg — light spinning leaders, trout and grayling
