Abstract
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 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, and such that the golf ball exhibits a lift coefficient (CL) of less than about 0.200 over a range of Reynolds Number (Re) from about 120,000 to about 180,000 and at a spin rate of about 3000 rpm.

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 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, and such that the golf ball exhibits a lift coefficient (CL) of less about 0.190 over a range of Reynolds Number (Re) from about 130,000 to about 180,000 and at a spin rate of about 3000 rpm, and
- wherein the first and second groups of areas and dimple shapes and dimensions are configured such that the golf ball exhibits a CL of less than about 0.180 over a range of Re from about 140,000 to about 180,000 and at a spin rate of about 3000 rpm.
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 comprising dimples 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 exhibits a lift coefficient (CL) of less than about 0.190 over a range of Reynolds Number (Re) from about 130,000 to about 180,000 and at a spin rate of about 3000 rpm, and
- wherein the plural areas are configured such that the golf ball exhibits a CL of less than about 0.180 over a range of Re from about 140,000 to about 180,000 and at a spin rate of about 3000 rpm.
