Abstract:
1. A multi-piece golf ball, comprising: an outer surface having a plurality of dimples configured to provide selected aerodynamic properties to the ball, and wherein the outer surface of the golf ball is divided into plural dimple areas comprising at least two bands which extend at an angle to one another around the periphery of the ball and cross over at two diametrically opposed locations and additional dimple areas defined between the two bands, the bands containing first dimples and the additional dimple areas containing second dimples, the first and second dimples having different dimple parameters; a core comprising at least one piece; a cover layer surrounding the core and comprising at least one piece; at least one piece of the ball having an at least partially non-spherical first surface which faces outwards; a second piece of the ball directly surrounding said first surface having an inwardly facing, second surface of complementary, at least partially non-spherical shape opposing said first surface; said at least one piece of the ball having a higher specific gravity than at least one other piece; the ball having first, second and third orthogonal axes; and the core and cover layer are configured such that the ball has a first moment of inertia (MOI) with respect to the first orthogonal axis which is higher than the MOI with respect to the second and third orthogonal axis.
