- 9. The golf ball of claim 1 wherein said center component of said multi-layer core has an outer diameter of from about 1.340 inches to about 1.400 inches, and said core layer of said multi-layer core has an thickness of from about 0.020 to about 0.100 inches.
- 10. The golf ball of claim 1 wherein said center component of said multi-layer core is softer relative to said core layer.
- 11. The golf ball of claim 10 wherein said core layer ha s a Shore D hardness of at least 60.
- 12. The golf ball according to claim 1 wherein each layer in the multi-layer cover (i) and multi-layer cover (ii) is independently formed from a thermoplastic resin, a thermoset resin, or a blend thereof.
- 13. The golf ball according to claim 2 wherein the multi-layer cover (i) or multi-layer cover (ii) comprises at least one ionomeric material.
- 14. A golf ball comprising:
a multi-layer core comprising a center component and a core layer disposed about said center component; wherein said center component comprises a polybutadiene thermoset material and said core layer comprises a polybutadiene thermoset material; and, a cover layer disposed about said multi-layer core; wherein said cover layer includes at least one of (i) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or greater and an outer cover layer having a Shore D hardness of 65 or less, said inner cover layer being harder than said outer cover layer, (ii) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or less and an outer cover layer of 65 or greater, wherein said inner cover layer is softer than said outer cover layer, and (iii) a single non-ionomeric outer cover layer having a Shore D hardness of from about 40 to 80, and (iv) a single ionomeric outer cover layer having a Shore D hardness of at least 56.
- 15. The golf ball according to claim 14 wherein the cover layer is selected from multi-layer cover (i) or multi-layer cover (ii).
- 16. The golf ball of claim 14 wherein said thermoset material further comprises zinc diacrylate (ZDA).
- 17. The golf ball of claim 14 wherein said core layer comprises more than one layer.
- 18. The golf ball of claim 14 wherein said center component of said dual core comprise is softer relative to said core layer.
- 19. The golf ball of claim 11 wherein said core layer has a Shore D hardness of at least 60.
- 20. A golf ball comprising:
a multi-layer core comprising a center component and a core layer disposed about said center component; wherein said center component comprises a polybutadiene/ZDA thermoset material and said core layer comprises a polybutadiene/ZDA thermoset material; and, a multi-layer, ionomeric cover layer disposed about said dual core; wherein said cover layer includes at least one of (i) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or greater and an outer cover layer having a Shore D hardness of 65 or less, said inner cover layer being harder than said outer cover layer, and (ii) a multi-layer cover comprising an inner cover layer having a Shore D hardness of 65 or less and an outer cover layer of 65 or greater, wherein said inner cover layer is softer than said outer cover layer.
