Dizzy's right, the max diff is .060. As far as the opinion of the immortals go, I have to say that I never had an issue with rollout with this ball. I am able to play just about any line, and have decent carry with it with proper coverstock adjustments. I will, however, make the disclaimer that I am speed dominant with average revs, and that some people could experience a rollout if they have tons of hand or slower speeds. This is not something I've experienced, and I absolutely LOVE the versatility of the coverstock.
