Scoot- Thanks for your explanation about symmetrical vs. assymmetrical. My questions still remains. What makes this ball (Maniac) symmetrical and not assymmetrical? From the looks of the core, it appears assymmetrical based on it doesn't seem it would be identical if one were to cut the core in half. I think what's throwing me off is those nubs. Thanks.
