My overall take on this is that the IQ was obviously way to rolly, lazy, smooth, early. While this is a really great tool for a bowler to have, it doesnt appeal to the masses. this ball also released a whole new coverstock for storm, and i think they would really like to see it work. So why not throw it on a much higher RG ball, to get it the core from burning up, hopefully giving the bowler the down lane motion that appeals to them.
I think storm policy indicates that a core/cover has to be out of the line for 2 years before it can be reintroduced (but i think the don carter/wiseman balls ruined that idea) so its perfectly acceptable to see the CAM core again.
