Golf ball with improved flight performance
First Claim
1. A golf ball having more than three layers, including an outer surface and a core, wherein the core has two or more layers, and wherein the outer surface comprises less than about 370 dimples and one or more polygonal dimples having at least six sides, wherein the golf ball does not have a great circle that does not intersect any dimple, wherein the total dimple volume is at least 1.5%.

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.
