<p><P>PROBLEM TO BE SOLVED: To provide a dimple design with superior performance in carry distance for golfers whose swing profile generates moderate to low ball spin rates defined here to be from 1500 rpm to 2600 rpm. <P>SOLUTION: A golf ball has an equator at latitude 0°and two pole, an equator region defined by latitudes 0°to 25°, a shoulder region defined by latitudes from more than 25°to less than 65°, and a pole region defined by latitudes 65°to 90°, and a dimple pattern on the surface having an average dimple volume of the equator region Ve, an average dimple volume of the shoulder region, Vs, and an average dimple volume of the pole region, Vp such that the ratio Vs/Ve is less than 0.97 and the ratio Vp/Vs is less than 0.97. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
