Dimple patterns for golf balls

A golf ball having a substantially spherical surface, comprising:

• a plurality of dimples disposed thereon, wherein the dimples are arranged in a pattern comprising four substantially identical dimple sections,
• wherein the dimples in each of the four substantially identical dimple sections comprise a first plurality of dimples having a minimum dimple diameter and a first coverage contribution, a second plurality of dimples having a maximum dimple diameter and a second coverage contribution, and a third plurality of dimples having an additional dimple diameter and a third coverage contribution, wherein the difference between each of the minimum dimple diameter, the maximum dimple diameter, and the additional dimple diameter is at least about 0.040 inches,
• wherein the third coverage contribution is at least about 40 percent and the third coverage contribution is greater than the first coverage contribution and the second coverage contribution, and
• wherein the dimples cover about 75 percent or less of the substantially spherical surface, and the pattern results in no dimple-free great circles on the golf ball.
