Good question. I originally thought I would pick contestants myself (just to make things a little random) but it might be interesting to have the winner of the last round pick someone to fight against. Of course that might be a little unfair because the winner might pick somebody who he can easily beat (like me).

Tell you what: the loser can pick who should fight the winner. He can send a PM to me containing the name of the person he wants the winner to fight next. That way nobody else would know and things will stay interesting.
