The vast majority of super low compression golf balls will be two pieces. This is because dealing with fewer parts makes it easier to create a softer golf ball. When the soft core is combined with a soft Urethane cover, the ball has very low compression. When you move to a three-piece golf ball, you will notice a significant increase in spin rate around the green. Higher compression golf balls are suitable for those that need greater performance around the green rather than distance off the tee.
