Claim:
1. A golf ball having a non-planar parting line about non-circular dimples on its spherical surface, the parting line comprising: non-concentric arcs having straight connecting line segments between the arcs, wherein each arc maintains a tangency with its connecting lines and a relief distance greater than or equal to 0.003 inches when measured from an average non-circular dimple diameter to one of the non-concentric arcs and an absolute relief distance of at least 0.001 inches when measured from all points on the non-circular dimple perimeter to one of the non-concentric arcs; and a radius of each non-concentric arc relates to a corresponding average non-circular dimple perimeter diameter according to the equations: wherein r μ and n≧25 wherein r
