Entertainment / Bowling / Dynamic Weights: In the old days, before the advent of modern core design in balls, the center of the ball was, more or less, symmetrical. In today's high tech computer designed ball cores and multiple cores designs, you can have cores that are not evenly balanced and distributed within the center of the ball; this allows balls to be drilled and designed in a manner that the apparent weight of the ball can shift depending on the drilling pattern; i.e., it is not static it is dynamic.
