I would lose it if I watched a CB roll like that on "professional" equipment! I would normally think it was the table, but in that last video the ball wobbles in both directions, unless the slate was not planed level I would blame the CB.
Did they actually glue those racks down! that sucks! I forget what match it was, but on the break the CB was rolling towards the nine sitting in the rack and was dead set to be frozen to it and leave a jacked up long one ball shot. CB rolled off in two spots on the rack and landed beside the nine leaving a much easier one ball, the rack was then ran pretty easily. I would have also lost my shit on that one as well!
I saw a lot of little rolls in this tournament. The equipment at my local hall seems to play more accurate than that. That's a shame!
