Balance (As Applied To A Ball): The weight of a bowling ball is not always evenly distributed in the sphere. ABC rules allow a ball to vary 3 ounces from the drilled top half to bottom half of a ball, and one ounce from the left to right side.Before resin balls, these weights were used to subtly change the roll pattern of a ball. A ball that has negative balances tends to be influenced to turn away from the pins; a ball with positive balance will be influenced to turn into the pins.
