1. A golf ball comprising:
- a solid core having an Atti compression, the core being formed from a composition comprising a diene rubber, a metallic fatty acid salt present in an amount of 6.3 to 7.5 per hundred parts diene rubber such that the compression increases by 4 to 10 points, a cis-to-trans catalyst, and an organic peroxide initiator present in an amount of 1.2 parts per hundred parts diene rubber or less; and
a cover comprising a polyurea that consists essentially of urea linkages.
