"A comparatively shallower head with thick wall makes the face look longer, thereby adding the sense of confidence at address. With a deep center of gravity, the 455 delivers a higher trajectory and longer distance. The high density cup face, featuring pleasant hitting sound and response, allows the user to feel the ball caught on the face. 450 of the operations-oriented ,455 of the straight trajectories-oriented.
With an appropriate spin, a stable and comfortable hitting feel is provided. The special high-density method is a multiple process. A two press process is added after hot-forming the face. It adds greater density to the metal texture of 6-4 titanium, thereby enhancing the rigidity of the material."
