Hi AZB, I bought this pool ball cleaner a while back off ebay for $100 + $20 for shipping.
It works really well however I have seen been given a diamond ball cleaner and do not need this anymore.
Here is a link to the ebay listing of who I originally purchased this product from...
HAHA, yea I cracked up as I was typing it. Glad he's a mature person and professional.
As far as the pattern racking, I would be surprised that either Ko would ever do something not within the rules. But I do not recall the match for certain.
