Sert Braid X8 135m – Fluo Yellow – 0.18mm 23lb

Take your casting performance and lure control to the absolute limit with the Sert Braid X8 135m (Fluo Yellow – 0.18mm / 23lb). Meticulously engineered using eight strands of premium high-modulus fibers, this ultra-smooth braided mainline represents the pinnacle of modern line technology for UK saltwater and freshwater predator tactics.

The advanced 8-strand weaving process creates a perfectly round profile with a silk-like exterior surface. This drastically reduces friction as the line flies through your rod guides, resulting in silent, frictionless casting and staggering distance gains. Finished in high-visibility Fluo Yellow, it allows you to track the exact path of your lure and detect the faintest line-ticks from a cruising bass or a cautious winter pike.

Gerry’s Pro Tip: “An 8-strand braid like this Sert X8 is all about pure performance and distance. Because it is so round and smooth, it handles beautifully and casts significantly further than a standard 4-strand line. To maximize its lifespan, make sure your rod guides are clean and free of salt crusting. When joining this super-slick braid to a fluorocarbon leader or wire trace, we highly recommend using a high-turn Albright knot or an FG knot to ensure a rock-solid, non-slip connection that glides effortlessly through your tip ring.”

Frequently Asked Questions

What is the main benefit of X8 (8-strand) over X4 (4-strand) braid?

An X8 braid uses eight finer strands woven together, creating a line that is much rounder, smoother, and softer than a 4-strand equivalent. This results in much quieter line flow through the guides and significantly longer casting distances. While X4 braid is slightly more abrasion-resistant against heavy gravel, X8 is the undisputed champion for pure casting distance and smooth handling.

Will the high-vis yellow line spook fish in clear water?

While the high-vis yellow color is an incredible asset for the angler to track line movement above the surface, it can be visible to fish in crystal-clear water. To counter this, simply tie a 3ft to 5ft leader of clear fluorocarbon to the end of your braid. This gives you the best of both worlds: ultimate line visibility for you, and a completely stealthy presentation to the fish.

Do I need to use backing on my reel spool with this line?

Yes. Because premium 8-strand braids are incredibly smooth and slick, the entire profile of line can spin on a bare metal spool core when subjected to heavy pressure from a big fish. Always put down a few wraps of cheap monofilament backing, or wrap a small piece of electrical tape around the spool center, to give the braid a secure foundation to bite into.
