Golf ball with resin inner core having specified coefficient of restitution of the inner core at various speeds

A golf ball comprising:

• an inner core layer, wherein the inner core layer comprises a first highly neutralized polymer with a first flexural modulus, a second highly neutralized polymer with a second flexural modulus, and a low flexural modulus ionomer, and wherein the inner core layer has a diameter between about 24 mm and about 30 mm;
• an outer core layer, wherein the outer core layer surrounds and encompasses the inner core layer, and wherein the outer core layer comprises a rubber composition;
• and
• a cover layer, wherein the cover layer surrounds and encompasses the outer core layer,
• wherein the first highly neutralized polymer is about 20 to 60 parts by weight of the inner core layer,
• wherein a ratio of the second flexural modulus to the first flexural modulus is less than 2,
• wherein the low flexural modulus ionomer has a flexural modulus of less than about 8,000 psi,
• wherein the low flexural modulus ionomer is from about 1 to about 50 parts by weight of the inner core layer,
• wherein the inner core layer has a first coefficient of restitution measured at 131 ft/s of about 0.810 to about 0.835, a second coefficient of restitution measured at 140 ft/s of about 0.805 to about 0.815, and a third coefficient of restitution measured at 160 ft/s of about 0.775 to about 0.790, where an average of the first coefficient of restitution, the second coefficient of restitution, and the third coefficient of restitution is at least 0.8.
