I too am a BoP, which means I stay Bish in the LW arenas. Like others have said, its not so much a loyality to a chess peice, but to the guys I have normal daily interaction with: The Flying Circus, Unforgiven, SEs, Ground Pounders, SwampDragons ect ect. That being said, when I pop into mid war, I go to the side with the least amount of people.
