Upgrade X8 has the most advanced material braided by the most advanced technology to offer great line. And, YGK explains it has the most tightly braided line among its braided lines. By the braid process, lines will have more abrasion resistance, but will lose some tensile strength. Upgrade has the improved abrasion resistance which gives super advantage on the line.
It has smooth surface and the smallest line diameter. It employs the most advanced filament, Ultra 2 PE, to achieve about 40% more maximum strength compared to standard spectra braided lines. On its surface, it has relatively thick coatings to prevent tangle and to protect line from abrasion. YGK WX braiding technology makes the line with the least stretch and tightest line body. The 8-strand body offers the smoothest line surface. Quality is proven. Hi-vis lime green, without markings, which is on the original Upgrade X8, to prevent line cutting for puffer fish to bite on them. Made in Japan.
