12 carrier HMPE braided line plus a single GORE Performance Fiber in the center for optimal roundness and reduced internal abrasion. Built with 13 fibers (12 HMPE fibers 1 GORE Performance Fiber in core) to guarantee consistently strong construction with no weak points for reliable braided line during casting, strikes and fighting action. Construction increases the number of fibers at the knot resulting in better knot tying and stronger holding power. A single strand of GORE Performance Fiber surrounded by 12 precision braided HMPE fibers results in a super-round line that is smoother and quieter than other lines.
