Golf ball with improved flight performance
First Claim
1. A golf ball having an outer surface, wherein the outer surface comprises less than about 370 dimples covering at least about 80% of the outer surface of the golf ball and wherein the dimples comprise at least two sizes and the golf ball has lift coefficient at Reynolds Number of 180,000 and spin ration of 0.110 of about 0.170 or less.

Abstract
A golf ball is provided that has improved aerodynamic efficiency, resulting in increased flight distance for golfers of all swing speeds, and more particularly for golfers possessing very high swing speeds, such as those who can launch the balls at an initial speed greater than 160 miles per hour and more particularly at initial ball speed of about 170 miles per hour or higher. The golf ball of the present invention combines lower dimple count with multiple dimple sizes to provide higher dimple coverage and improved aerodynamic characteristics.
