Nike has a new top-of-the-line golf ball that has appeared on the PGA Tour and should be available for consumers later in the spring. This ball, called the 20XI Prototype, will become the 20XI when it hits retail shelves. At Kapalua, it was used by Anthony Kim, Francesco Molinari and Carl Pettersson.
The ball is unique because it has a core made of lightweight resin. This allowed Nike engineers to reposition a small amount of weight nearer the outside of the ball. Players in Hawaii used the S (spin) version. Eventually, an X (distance) version will be available and we will have ball fitting available with both balls this spring.
