TopShelf2010: Many of the balls have "new" names. While not necessarily a new ball, the name is different with the same specs. For example, all of the Volvic balls are now listed a Volvic Vivid. Even the Callaways Chromes have different names Soft X or E R C Soft.
Yes, that was how i first noticed, as I couldn't make an 'in game' purchase. BUT I can't buy ANY ball, even ones that haven't changed their names.
My regular ball HAS changed its name and I tried to buy another similar spec ball that hasn't changed.
