Mafia Wars Global Cup collectible balls -- an offer you might refuse

Mafia Wars Global Cup event has officially ended (as of midnight, June 24) -- but you can still buy limited edition collectible balls in the Marketplace. Each costs five Reward Points and each has different stats, some more defensive and other more offensive. We'll have those stats for you soon.

From what I've seen on these stats-wise -- unless you're one of those people who absolutely have to collect EVERYTHING in Mafia Wars (or really love soccer), you might want to save up those Reward Points for something with a little more kick. You dig?

Which Collectible Balls did you purchase? Do you think they're worth the Reward Points?
