We've seen a few. Some were faded colors (alot of phazing in the Philadelphia Eagles and Pittsburgh Steelers 2nds I've seen on the east coast), and some were as simple as midweights like 15lb 10-12 oz.
Kinda a grab bag. On a Viz, I think it'd be hard to sell a customer if it looked bad. If they're really cheap you can always throw them on the Haus and sell them as "Cue Balls" at a discount.
