I kept mine in box surface for awhile, worked great on most medium-heavy oil conditions, especially on the fresh. When the head oil pushes a bit, carrydown can be a tricky proposition with the ball. I just adjusted the surface to 500 grit as well for the nights when I need to get some more friction generated, we'll see how that goes. Good luck with the ball and let us know how it works out.
