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