I'm considering a new set of pool balls and am set on Brunswick Centenials. Upon looking in the internet, I l discovered that there are the following; Brunswick Centenial Pocket Balls Premium Edition, and Standard Edition. However, the box looks the same and does not indicate premium or standard. In fact, the boxes look the same and have the Brunswick logo and below indicate Precision Balanced Pocket Balls and up in the left indicate Centennial. Moreover, the price range is significant from $449.00 a set to $369.00 for standard edition! My local pool shop sells new Centenials for $245.00 a set. The balls are sold as new in the box but have a yellow tint while in the internet the premiums appear as brilliant white. Can someone please shed light on this topic?
