The F1st-66XS "Kirisame" series is a new basic from the 5D graphite system. Using light finesse rigs for almighty, the development team testing rating records a balanced performance chart for every element as a finesse rod. Outstanding usability. We focused on smoothly moving the load from the butt section that eliminates the feeling of bending shift between the extra fast tip and belly section, and the butt section that produces overwhelming high torque far beyond the previous drizzle model. The result is "easy to throw", "smooth sweep hooking", and "strong lifting power" that cannot be used as a pre-toned rod. As a Finesse Spin, we aimed at a new era of global basics.
