Really nothing bec so far I can't think of a reason. If I had to pick one it would be bec it only 4 multiball bec 4 band members and maybe I should wait for Iron Maiden if its ever made which should have 3 and 6 mutiball bec they have 6 band members. I want to see if anyone has good reasons not to buy this pin. I really think this could be a great first NIB selection.
