Selection process for EHBPC 2011 23-26.06.2011

It seems to me that swiss rounds is the least bad option in terms of fairness when you have a lot of teams to schedule, but round-robin is faultless. So more tournaments with fewer teams is fairer. What's a realistic number to do round-robin in one day, 8? 10?

Maybe 20 teams in the UK interested in going? 7-10 in London, maybe a bit more outside London? Could work.

With 10 teams, it is 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45 games or 450 mins of game play, based on 10 mins / game, no golden goals.
