Abstract:
1. A golf ball consisting of: a core comprising an inner core and an outer core disposed over the inner core, the inner core having a deflection of at least 0.230 inch under a load of 220 pounds, and the core having a deflection of at least 0.800 inch under a load of 200 pounds; an inner mantle layer disposed over the outer core, the inner mantle layer having a thickness ranging from 0.070 inch to 0.090 inch, the inner mantle layer composed of an ionomer material, the inner mantle layer material having a plaque Shore D hardness ranging from 36 to 44; an outer mantle layer disposed over the inner mantle layer, the outer mantle layer having a thickness ranging from 0.025 inch to 0.040 inch, the outer mantle layer composed of an ionomer material, the outer mantle layer material having a plaque Shore D hardness ranging from 65 to 71; and a cover layer disposed over the outer mantle layer, the cover having a thickness ranging from 0.025 inch to 0.040 inch, the cover composed of a thermoplastic polyurethane material, the cover material having a plaque Shore D hardness ranging from 40 to 50, and the on cover Shore D hardness less than 56; wherein a dual core deflection differential of the inner core having a deflection of at least 0.230 inch under a load of 220 pounds and the core having a deflection of at least 0.800 inch under a load of 200 pounds allows for a low spin of a golf ball hit off a tee to provide greater distance, and a high spin of a golf ball hit on approach shots.
