Abstract: A high performance golf ball having a reduced overall distance while maintaining the appearance of a high performance trajectory. The golf ball includes a combination of low CoR core and cover materials coupled with a less efficient aerodynamic dimple pattern that achieves a reduction in carry and overall distance of at least 5 yards versus a conventional golf ball, while still providing the look, sound, feel and apparent flight of a conventional golf ball. A high performance golf ball having a reduced distance is also achieved by maintaining the lift to weight ratio to be greater than 1.5 at a Reynolds number of about 205,000 and a spin rate of 2900 rpm.
