The Best of Both Worlds
The Tour i and Tour ix Golf Balls react differently off of a driver than off of shorter irons such as wedges. When the ball is struck with a driver, the impact is strong enough for the force to reach the inner core of the golf ball. The inner core is soft, allowing the ball to compress, or deform, which prevents the ball from spinning as much.
However, when you hit the same ball with a wedge, the force is not great and the firmer, outer core helps the ball retain its shape, enabling more spin to be generated by the club catching the soft cover.
