just get rid of the prelim set :P
BHA or Stve picks captains 1, 2, 3, 4 (pick from a hat which captain goes to what team number)
then just do 1 vs 4, 2 vs 3 or whatever....
then finals for the winners, consolations for the losers...
although a 3 game prelim isn't bad either.... but maybe do that for the next tourney when it will hopefully be larger (so the prelims actually MEAN something)....
so 4 matches in the one night, instead of 10 (if my math is correct) like you propose Narf....
either way
