Golf ball having high initial velocity

A golf ball comprising,

• an inner core layer;
• an outer core layer enclosing the inner core layer;
• an inner cover layer enclosing the outer core layer;
• an outer cover layer enclosing the inner cover layer;
• wherein performing the 125 mph head speed test on the golf ball results in the golf ball having a first initial velocity;
• wherein performing the 80 mph head speed test on the golf ball results in the golf ball having a second initial velocity;
• and
• wherein the first initial velocity is about 85 mph to about 87 mph higher than the second initial velocity.

A golf ball comprising,

• an inner core layer including at least one first highly neutralized acid polymer composition;
• an outer core layer enclosing the inner core layer;
• an inner cover layer enclosing the outer core layer;
• an outer cover layer enclosing the inner cover layer;
• wherein performing the 125 mph head speed test on the golf ball results in the golf ball having an initial velocity ranging from about 173 mph to about 174 mph;
• and
• wherein performing the 95 mph head speed test on the golf ball results in the golf ball having an initial velocity ranging from about 115 mph to about 117 mph.
