Abstract:
A three-piece wound golf ball having improved characteristics of moment of inertia, initial spin and total flight distance with minimal dispersion, the ball comprising:a solid center core portion which is substantially spherical, is composed mainly of polybutadiene having a core diameter of 1.35-1.50 inches (34.3-38.1 mm), a specific gravity of 1.23-1.24, a Shore D durometer hardness of 55-75 and a compression of 59-75 on an Atti compression tester; an intermediate thread-wound portion wound with an elastomeric thread material upon said core portion to a diameter of 1.540-1.600 inches (39.1-40.6 mm); and a cover portion formed of a thermoplastic material having a density of 1.00-1.04 g/cm3, and a Shore D durometer hardness of 55-65, said cover having multiple dimples provided therein; the ball having an outside diameter of 1.680-1.688 inch (42.7-42.9 mm), a weight of 44.5 to 45.9 grams, a density of 1.090-1.118 g/cm3, and an Atti compression reading of 85+/âˆ’15 points.
