发明名称 GOLF BALL WITH LARGE CENTER CORE
摘要 A golf ball is disclosed that provides a softer feel, resilient core for decreased spin rate. The golf ball has a dual-layered core surrounded by a dual-layered cover. The volume of the inner layer of the dual layer core is at least about 70% of the total volume of the inner core layer and the outer core layer. The inner core has a diameter from about 1.25 inches up to about 1.55 inches. The outer core has a diameter from about 1.55 inches up to about 1.62 inches. The compression of the dual core is from about 60 to about 100. The outer core layer is constructed from materials that provide for a Shore C hardness of at least about 80. The dual-layer cover includes an inner layer having a Shore D hardness of at least about 60 and a thickness of about 0.015 inches to about 0.055 inches. The outer core layer has a Shore D hardness of about 62 or less and a thickness less than about 0.035 inches.
