ST5 is Westin's softness rating for fluorocarbon leaders. It indicates maximum flexibility and supple handling while maintaining full knot strength. This makes W6 ST5 easier to work with than stiffer ST1–ST3 alternatives, particularly when tying knots and managing the line from spool.
Choose diameter based on your target species and lure weight. Lighter diameters (0.14–0.38mm) are ideal for finesse presentations and small lures for perch and trout. Medium sizes (0.44–0.62mm) suit general spin fishing for pike and perch. Heavy diameters (0.92–1.20mm) are designed for large predators, aggressive lures, and cutting through weeds. Match the breaking strain to your reel and casting technique.
W6 ST5 is made from 100% clear fluorocarbon. Fluorocarbon has a refractive index very close to water, making it nearly invisible to fish below the surface. This is especially important in clear water and when targeting wary predators that inspect the leader closely.
W6 ST5 is a fast-sinking fluorocarbon leader, meaning it sinks quickly to take the lure down without resistance. This is standard for predator fishing and ensures the leader stays below the surface rather than floating or creating surface drag.
Spool lengths depend on diameter. Lighter lines (0.14–0.38mm) come in 50m spools, suitable for extending long fishing sessions without frequent changes. Medium diameters (0.44–0.62mm) are available in 25–35m spools. Heavy diameters (0.92–1.20mm) come in 20m spools, which is typical for pike and musky work where durability and frequent inspection matter more than total length.

Westin W6 ST5 Fluorocarbon is a supple, abrasion-resistant leader material engineered for modern predator fishing. With its exclusive production process and low memory effect, it combines sensitivity with knot strength across a wide range of diameters and breaking strains.
The ST5 rating delivers maximum flexibility while maintaining exceptional knot and tensile strength. This balance allows both fine presentations with ultra-light diameter lines and confident casting with heavier leader material. The 100% fluorocarbon construction provides invisibility underwater, critical for spooky fish. Soft and supple handling reduces memory effect compared to standard fluorocarbon leaders, making the line easier to manage from spool to knot.
All sizes in this range share consistent performance characteristics: fast sinking behavior, high abrasion resistance, and incredible knot strength. Diameter sizes range from 0.14mm (ultra-fine trout work) to 1.20mm (pike and musky leaders), with breaking strains from 1.3kg to 62kg. Available in spools of 20m to 50m depending on diameter, allowing you to choose the right setup for your target species and fishing style.
Ideal for spin fishing, pike, perch, and sea trout. The clarity and softness make W6 ST5 equally effective in weedy environments and clear water. Smaller diameters suit finesse presentations and light-tackle work, while heavier sizes handle aggressive lures and large predators.
