A golf ball with a precise spin rate is disclosed. The distribution of weight among the layers within the golf ball relative to a centroid radius is realized to precisely control the moment of inertia of the ball. In accordance to one aspect of the present invention, a high spin rate golf ball with a dense center, which is positioned radially inside of the centroid radius, and a low specific gravity mantle is provided. In accordance to another aspect of the present invention, a low spin rate golf ball with an inner core and a thin dense layer disposed radially outside of the centroid radius is provided.
