A flying distance and operability
Modern muscle and RZN (resin) technology
It is a baud by energy efficiently by matching a center of gravity position with the center of the face
I communicate with ル. I improve stability, the feeling of the head and realize solid 打感.
Weight surplus in RZN (resin) in the thing adopting more widely of the head after a head
I locate it in the lower and it is deep and designs the center of gravity position low. Of a high repousse angle and the quantity of spin most
I realize flying distance up by 適化. The moment of inertia to contribute to the stability of the shot improves.
