There are some minor differences, but overall, that core rolls so well that the ball is still a winner. I would get it if you were looking for one and had the opportunity to purchase it. On a side note, I also had a Track Havoc and that is the same ball as the black Nighthawk. When Del went from AMF to Track he took some staffers with him and they wanted the Nighthawk, so because Columbia produced AMF and owned Track, they made the Havoc.
