I would agree with ice, provided both surfaces were out of box. I never had an UI for myself, and only drilled one for a customer, but that ball does tend to rev very early. When the heads start to go, sa does the UI. The Rule will be much more playable overall for you. Although dry heads are NOT the Rule's forte, the reaction will gradually go away, not all of a sudden like with the UI from what I have seen.
