Justice took 2nd in 2011, 1rst in 2012. We'll be happy to return again for this fantastic cause and defend the title for Xander.
As far as suggestions, as long as I have paint, and a target to shoot at, it's going to be a great time no matter what. I'm not against keeping it as a 3 man speedball event. But if you wanted to switch it up, perhaps a competitive way to play woodsball would be fun.
How bout an attack and defend? put an air horn in a box, with a combination lock. 10-15 minute game. Award points for bodies, and objective complete. You could get as creative as you want with it for extra points. Flawless victory awarding double points, throw in additional props to be recovered, ect.
Just a start for suggestions, I'm sure many other rec ballers could throw in much better ideas.
