Abstract:
1. A golf ball having a plurality of dimples formed on its outer surface, the outer surface of the golf ball being divided into plural areas, a first group of areas containing a plurality of first dimples and a second group of areas containing a plurality of second dimples, each area of the second group abutting one or more areas of the first group, the first group of areas containing only first dimples and no second dimples, the second group of areas containing only second dimples and no first dimples, the first and second groups of areas and dimple shapes and dimensions being configured such that the golf ball is spherically symmetrical as defined by the United States Golf Association (USGA) Symmetry Rules, the plural areas configured such that the golf ball has a Drag Coefficient (CD) and a Lift Coefficient (CL) of less than about 0.330 and 0.270, respectively, at a Reynolds Number (Re) of about 80,000 and a spin rate of between about 2,900 rpm and about 3,000 rpm and a CD and CL of less than about 0.260 and 0.155, respectively, at a Re of about 170,000 and a spin rate between about 3,420 rpm and 3,520 rpm, and the first and second dimples having circular peripheries at the outer surface of the golf ball and the first dimples all being of smaller diameter than the second dimples.
