Uses triple shield finish (T, S, F) for basket and casting. Further evolution of CN (Carbo Nylon), which has excellent sensitivity, durability, and usability . In addition to improving water resistance and durability, it also adds lubricity and water repellency to reduce heat generated by friction and maintain initial performance. What is Carbon Nylon? 〉Fluorocarbon x Nylon = Carbon Nylon A hybrid line that combines the operability, long-distance casting performance, and straightness/knot strength of nylon with the low stretch and high sensitivity of fluorocarbon.
