Perfecone,
My Uranium had the exact same mark! I got it NIB from a reputable seller, and I had the same half-moon shape mark that looked like it had been plugged. There were also a couple of small chips. I assumed they were from rough shipping. I think that this is a Lane 1 issue, and not a seller issue. Thankfully for me, none of the marks were in the track and none were significant, but it did take me back a bit too.

Bowling is without a doubt the dumbest, most pointless, most idiotic excuse for a game that has ever been invented. So, what time are we bowling tomorrow?
