<p><P>PROBLEM TO BE SOLVED: To provide a golf ball having improved aerodynamic efficiency, whereby a longer drive can be achieved by any golfer at any swing speed, especially a fairly high-speed swing player, or more concretely, the one who hits the ball at about 180 miles/h (290 km/h) so that the original speed of the ball exceeds 160 miles/h (257 km/h). <P>SOLUTION: This golf ball has fewer dimples of various sizes which cover larger area on the ball surface, to improve the aerodynamic characteristics. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
