Any good GB clans for Black Ops?

I am looking to be part of a clan, I have two accounts, on one my KDR is 1.70, on the other it is 2.56. The reason being I mess around on my other account a lot with weapons (i.e. ballistic knife, crossbow, quickscoping). The other account is where I play serious as I would in a clan, so if you have any suggestion I would appreciate it. My Xbox Live Gamertag is ---> TNTthomas45
