Often the advantage of these urethane covered balls vs. ionomer or Surlyn-covered balls was 800-1,500 rpms of spin. What does that difference mean in terms of proximity to the hole? A little or a lot. Depends firstly on how firm the greens are: the firmer the green the more spin can be beneficial in stopping the ball. It’s also noteworthy that the lower spinning balls tend to launch higher so that may help them stop after landing because of their steep angle of descent, particularly in the greens are not firm. Still, the Foresight Sports ball-flight simulation software suggests that the spin difference might mean 15-18 feet of extra rollout after landing compared to the highest spinning balls.
