Abstract
Abstract Two or three piece molded type golf balls having click and feel similar to wound type balls of equal compression. These balls feature an elastic center having a minimum compressibility of at least 10 percent greater than the contacting synthetic elastomer composition which is highly resilient and has a minimum Shore A Durometer hardness of about 70. The softer elastic center such as plastic elastomer or rubber, plastic or rubber foam, natural or composition cork, etc., allows each ball to flatten more under club impact, to reduce likelihood of ball breakage, and provide for excellent click and feel. When the center is made of low density material, more weight is allowed to be concentrated within the outer portion of the ball to provide a ball exhibiting reduced hooking and slicing action when improperly hit.
