R8 Precision Braiding and fiber technology provide superior strength, roundness and line consistency. Patent-pending construction of 8 fibers (7 HMPE fibers plus 1 GORE® Performance Fiber) and 32 weaves picks per inch. GORE® Performance Fibers improve abrasion resistance, increase casting length/accuracy & reduce line vibration. HMPE fibers provide high strength & sensitivity, small diameter & hydrophobic water-repellent protection.
