You guys really need to stop turning every thread into a conversation about me - it is not helping my monstrous unjustified ego at all.
XBall is actually pretty easy to play at nearly ALL locations. The field dimensions are easier to accomodate than 7-man field dimensions. Beyond that, you just need a set of airball bunkers of about the right size. And those same two things go for 7-man as well. For running events, add a laptop and an airhorn to the mix and you're set.
But more importantly, the idea that EVERYONE must play the same format is just simply not true. It's definitely not true in other sports either. Everyone needs to be on the same format PATH. In baseball, you play tee ball, little league with 5, then 7 innings, etc. Soccer you scale up from 7 players in Kindergarten to 11. Even football scales.
For the XBall format, you start people out on 3-man or 5-man, and then they move up to XBall when they have a team that is ready for more organized competition. Or they just keep playing 5-man, if that's what they like.
And even better, you don't even have to take my word on it - we've already proved it. NCPA takes teams, starts them off in 5-man, and moves them up to XBall. Our teams have never had any trouble being able to practice or hold events.
