  • Publication number: 20110294602
    Abstract: A non-conforming golf ball has a plurality of dimples formed on the outer surface of the ball in a predetermined dimple pattern, the outer surface comprising one or more first areas which include a plurality of first dimples which together have a first dimple volume and at least one second area having a dimple volume less that the first dimple volume, the first and second areas being configured to establish a preferred spin axis. The second area may be a band around the equator which has a lower dimple volume or no dimples, with the polar regions have a higher volume of dimples, creating a preferred spin axis through the poles.
