    摘要： A golf ball is provided having a modified density gradient among the inner layers to produce a desired high or low moment of inertia and controlled spin rate is disclosed. The golf ball has three or more inner layers in addition to a cover, and the density of the inner layers is selected such that the layers inside the cover have a density progression from the core to the cover or from the cover to the core.

    摘要： A high performance golf ball having a reduced overall distance while maintaining the appearance of a high performance trajectory. The golf ball includes a combination of low CoR core and cover materials coupled with a less efficient aerodynamic dimple pattern that achieves a reduction in carry and overall distance of at least 5 yards versus a conventional golf ball, while still providing the look, sound, feel and apparent flight of a conventional golf ball. A high performance golf ball having a reduced distance is also achieved by maintaining the lift to weight ratio to be greater than 1.5 at a Reynolds number of about 205,000 and a spin rate of 2900 rpm.

    摘要： A golf ball with a controlled moment of inertia and controlled spin rate is disclosed. The ball has an intermediate layer positioned between the core and the cover and the intermediate layer has a reduced specific gravity. Preferably, this reduction is less than about 30% in specific gravity and the reduction in the coefficient of restitution is less than about 2%.
