Abstract
A golf ball comprising an inner core, an outer core, and a cover is disclosed. The outer core surrounds the inner core, and the cover encases the cores. The inner core is preferably a pre-formed selectively weighted symmetrical, but non-spherical insert, which may be made from either a high or low specific gravity material to control the moment of inertia and spin rate of the ball. The outer core is over-molded around the pre-formed insert to form a spherical core. Alternatively, the inner core insert has outer pockets defined thereon. These pockets are adapted to receive the outer core materials, which may have either a high specific gravity or a low specific gravity.
