If we ignore the fact that in 2011 year we got second in 2 regionals where we lost to the winning alliance by less than 5 pts, and in both cases a mini-bot decided it didn't want to work, I would have to say this match. During autonomous the uber-tube opened our pneumatic valve, so we had no pressure, and we were eventually able to put the tube we had onto the rack, but that was basically it the whole match. If it hadn't been for that mistake, we probably would have ranked second instead of third. Oh well.
