3v3?

5 other friends and I are planning a LAN party and we wanted to have a mini tf2 tournament

None of us are particularly good at the game, we can all topscore in pubs but nowhere near competitive level

Because there are only 6 of us, we'd have to do 3v3. Do you guys think we could make this work? What maps do you think would be best?

Any advice or tips for making this work would be helpful. Thanks guys
