Abstract:
A golf ball having a reduced distance while maintaining the appearance of a normal high performance trajectory. The golf ball has a core, an inner cover layer, and a cover. The core has a diameter of from about 1.300 to 1.620 inches, while the ball has a weight from 1.30 to 1.620 ounces, a diameter from 1.670 to 1.800 inches and a maximum Coefficient of Restitution from about 0.600 to about 0.790 as measured at 125 ft/sec incoming ball velocity. The ball has a lift to weight ratio of greater than 1.5 at a Reynolds number of about 207,000 and a spin ratio of about 0.095.
