Abstract
A golf ball (20) having a plurality of primary dimples (50) with annular tubular portion (60) is disclosed herein. In a preferred embodiment, there are 332 primary dimples which cover a surface area ranging from 81% to 87% of the golf ball (20). Also in a preferred embodiment, there are twenty different types of primary dimples (50), which vary in diameter, chord depth and/or entry angle.
