How many players for 12U tournament team?

First off, where are you? I'd love to play if you're anywhere close.

Secondly, I'd lean more towards 12-13. I coached in the 12U Babe Ruth states this past year and was really sold on the benefits of a deep bench. I'm leaning towards 13 for my 12U team next season with #12 and 13 being strictly pitchers. They'll be the #3 and 4 pitchers, but it will really make us a stronger team by allowing the other players to concentrate on their spots. Another good thing is to allow for vacations, injuries, ehections, etc. If you are playing a tourney with the EH and you only have 10 on the roster, you're sunk if anyone gets hurt or ejected. Likewise if anyone is sick or gets lost on the way to the park. I'm going with this set-up unless someone changes my mind:

4-OF
2-Pitchers only(both can PH)
2-3B/C-the 2 players will alternate
1-1B
1-2B
2-SS
1-UI/PR

My best SS is my #2 P and my RF is my #1 P (they also bat 3,4). Alot of our tournaments use the 10 batters, so I'll still only have 3 guys on the bench, 2 of which are strictly pitchers anyway.
