The idea of staged game to demonstrate skills/moves is good, but can be taken too far. You want to show what this format of paintball is like to play, not put on an episode of eastenders. In short: lots of fancy runthroughs and dives, no drama.
Another thing you could do (I'm sure it's been mentioned) is a short one on one tournament. It's easier for spectators to follow because theres less going on, and the focus is only on two players.
Skip it to 8:20 to see what I mean.
