Golf ball with resin inner core and specified inner core and cover layer hardness

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 about 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 golf ball has a ball compression ranging from about 3.0 mm to about 4.0 mm when measured with an initial load of 10 kg and a final load of 130 kg,
• wherein the inner core layer has a first surface hardness and the outer core has a second surface hardness, and wherein the first surface hardness is greater than the second surface hardness,
• wherein the second surface hardness is less than about 50 Shore D, and
• wherein the cover layer has a third surface hardness, wherein the third surface hardness is less than about 68 Shore D.
