I voted 16 and younger. However, I was torn between 14 and under and 16. I've played regular tournaments with kids that young and younger, and to be honest, we pretty much rolled them. Especially the teams with kids younger than 15. They just seemed to be getting started and just learning the ropes, so it really wasn't right for all the older teams to beat up on them. Sure, there are pretty experienced 16 year olds, but for the most part, the ones we played against didn't seem tournament "ripened", to coin a phrase, yet.
