I got some PM help from 'Cracktherack'. Thanks guy.
The help was not so much about the 'funny spins' but the info helped in my mind any way.
The Red Circle ball is made from a different resin. It's bouncier, 'hotter'.
That explains some things to me about how it has been coming off the other balls.
I just thought I'd put the info on here in case anyone else was interested.
Regards,
