Abstract
The present invention is directed to improved regulation multi-layer golf balls. A smaller and lighter core is produced and metal particles, or other heavy weight filler materials, are included in the cover compositions. The resulting molded golf ball exhibits enhanced interior perimeter weighting. Preferably, the particles are included in a relatively thick inner cover layer (or mantle) of a solid, three-piece multi-layered golf ball. The size and weight of the core is reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. The combination of the present invention produces a golf ball with an increased moment of inertia and/or a greater radius of gyration and thus generates lower spin. This results in a golf ball exhibiting enhanced distance without substantially effecting the feel and durability characteristics of the ball.
