Grip Size...2 Gender...Men's + Boys' Weight (g)...305 - 319.9g Compared to the Pro Staff, the frame has rounded corners, creating flex and a holding feel, making it easier to handle and more suitable for Japanese players. Being a 1-inch long type, it improves serve power and speed, and is also good for those with a two-handed backhand. With a black, red, and gold frame, it has a color scheme not seen recently, so I often received compliments like "That's cool!" when using it.
