That's the commercial... Everything was the same with the exception of the core design at the end.
Looks like a squat pear shape with 4 gouges in it in line with the high RG axis. DV8's Marauder core comes to mind, only with some difference in number of gouges/slits and a difference in those removed areas that might lead to an asymmetric core.
I couldn't nail down what ball Liz was using before she changed balls... I'd have to guess it was an IQ now that I did a little more research.
