Westin W6 ST3 Fluorocarbon 0.14mm 50m 1.4kg Clear

Westin W6 ST3 Fluorocarbon — Near-Invisible Leader Line for Light-Line Fishing

At just 0.14mm with a 1.4kg breaking strain, this 50m spool of Westin W6 ST3 Fluorocarbon (Stiffness Tier 3) is built for finesse tactics where low visibility and reliable knot strength matter most.

Low Visibility Where It Counts

Fluorocarbon has a lower refractive index than monofilament, meaning it bends light similarly to water and becomes significantly less detectable to fish underwater. For clear-water fishing or cautious species, this edge can make a real difference without any change to your presentation.

Fast-Sinking with Dependable Strength

The W6 ST3 sinks quickly, getting your rig into the strike zone faster than a floating mono leader. Despite the slender 0.14mm diameter, the line delivers exceptional knot and tensile strength alongside solid abrasion resistance — qualities that matter when fishing around light structure or over gravel.

Choose the Right Variant

The W6 ST3 range spans from ultra-fine leader material to heavy shock-leader and big-game diameters. The ST3 (medium stiffness) rating balances sensitivity with knot durability across all sizes. Match the diameter and spool length to your target species and technique:

• W6 ST3 50m 0.14mm 1.4kg — finesse fishing, light dropshot, trout, perch, clear stillwaters

• W6 ST3 50m 0.17mm 1.7kg — general light leader use, small rivers, panfish

• W6 ST3 50m 0.19mm 2.2kg — step-up for slightly larger species or snaggy bottoms

• W6 ST3 50m 0.219mm 3.4kg — predator fishing, zander leaders, medium spinning

• W6 ST3 50m 0.26mm 4.5kg — pike trace material, general predator leaders

• W6 ST3 50m 0.30mm 6.1kg — heavier pike and bass setups, boat fishing

• W6 ST3 35m 0.343mm 7.9kg — short leaders for heavier lure work, saltwater inshore

• W6 ST3 30m 0.38mm 9.3kg — boat and shore fishing, medium saltwater species

• W6 ST3 25m 0.44mm 11.6kg — offshore and heavy freshwater, catfish rigs

• W6 ST3 35m 0.52mm 16.4kg — big-fish leader material, specimen work

• W6 ST3 35m 0.62mm 26.1kg — heavy saltwater shock leaders, big catfish

• W6 ST3 20m 0.92mm 49.2kg — extreme big-game and catfish applications

• W6 ST3 20m 1.05mm 56.5kg — heavy offshore leaders and traces

• W6 ST3 20m 1.20mm 64.2kg — maximum diameter, big-game saltwater use
