ULTIMATE EVOLUTIONULTEGRA is popular among many anglers because of its rotational performance and durability beyond the standard for its price range. CORESOLID series design, which pursues smoother and more stable winding, shows its true value especially in fishing that continues a lure with large pull resistance such as a vibration plug at a constant speed. The basic performance was further upgraded with the addition of INFINITYXROSS, INFINITYDRIVE, and ANTITWISTFIN, resulting in satisfactory usability not only for entry-level users, but also for core users.
