Mantle surface topography for optimum energy transfer in multi-layer golf ball

A mantle assembly comprising:

• a core;
• a first mantle layer disposed about the core, the first mantle layer having a protuberant surface defined by a plurality of projections;
• and
• a second mantle layer disposed about the first mantle layer, the second mantle layer having a protuberant surface defined by a plurality of projections.

A golf ball comprising:

• a core;
• a first mantle layer disposed about the core, the first mantle layer having a protuberant surface defined by a plurality of outwardly extending projections;
• a second mantle layer disposed about the first mantle layer, the second mantle layer defining an inner surface layer and an outer surface layer, the inner surface layer defining a plurality of depressions, the outer surface layer having a protuberant surface defined by a plurality of projections;
• and
• a cover layer disposed about the second mantle layer, the cover layer defining an inner surface layer and a dimpled surface layer, the inner surface layer comprising a plurality of depressions, wherein
• the depressions on the inner surface layer of the second mantle layer correspond to the projections of the first mantle layer, and the depressions on the inner surface layer of the cover layer correspond to the projections of the second mantle layer.

A golf ball comprising:

• a core;
• a mantle layer disposed about the core defining a protuberant outer surface configuration provided by a plurality of stepped projections;
• and
• a cover layer disposed about the mantle layer.
