Love my Vibe, but it is not good on the fresh oil. I am very pleasantly surprised with a new Columbia Rival I just picked up. With some foot and hand adjustments this ball seems to handle heavy to light oil. I find it much easier to control than other medium-heavy oil balls I've tried, including the Gravity Shift, Break Pearl, and Venom.
I read somewhere that Chris Barnes said the Rival handles 80% of the lane conditions he sees. Just a thought.
