I have just got a used Hyper Zone and is drilled the same as the Vapor Zone with pin above bridge. In my opinion, the Hyper's reaction is more of slid slap where else the Vapor is more of an arc.
I also found that the Hyper is a much stronger ball especially in the backend.
Just my little observation. Anyone else has these two balls and would like to comment ?
