By adopting the "CORE-INPUT" manufacturing method, we have achieved moderate tension and a higher level of durability. In addition, the thread is less likely to collapse due to tension or pressure, so you can safely engage in forceful fights with big fish. Compared to conventional SP-T coating, the durability and low water absorption performance of the resin film are significantly improved. * Improved water repellency provides high performance. Succeeded in achieving outstanding straightness and ultra-low elongation of 3%. Significantly reduces line ``deflection'' and increases fall speed and sensitivity. It also allows for a more direct jig operation feeling.
