Although it is 1/4 heavier than iron, it is 10 times stronger, light and strong, and not easily deformed. It can be used for a long time with a strength that cannot be achieved with a nylon resin shaft. It has a luxurious feel with the gold logo, so it's also recommended for those who are particularly into higher-end settings.
It is a type of wave with a closed peak as opposed to the L-wave which has an open peak. Because it is made of carbon material, the opening of the four-sided part is inflexible, so the flight holding power is the best among the many waves. It will be difficult to exit the flight without a ring.
