Abstract
The present invention is directed to a golf ball with a core and a cover layer surrounding the core. The golf ball preferably has a weight between about 1.45 ounces and about 1.57 ounces and the core preferably has a diameter of greater than about 1.58 inches. Thus, forming a lightweight golf ball with an oversize core. In a ball with a thermoplastic cover, the core preferably has a diameter of greater than 1.61 inches. In a ball with a thermoset cover, the core preferably has a diameter of greater than 1.58 inches. This golf ball is specifically designed to optimize its play characteristics for low swing speed players. The golf ball may further include an intermediate layer disposed between the core and the cover.
