Travis,
I believe your intentions are to play in the World Series in Florida this year??? I would not recommend jumping in 12U tourneys primarily due to the difference in pitching distance and the size of the ball. If you are going to prepare, prepare for the culmination of your season. That is why 'coach' is attached to the end of your name. Define those expectations for your kids and parents.
We just playing in West Portsmouth this past weekend. Pitching was average, but we had the opportunity to see teams from WV, KY, OH and TN.
Over half of my team is able to play 10U this year, but we decided to keep this group of girls together for JH/HS ball down the road. I know going to a 12" ball and throwing at 40' has been an adjustment for my daughter (10). Many factors to consider...hand size, stamina, losing effectiveness of the changeup due to loss of some speed on the fastball, can they handle getting hit more (psychology), can your defense sure up the left side of the field to support your pitching, etc.
Just a few I saw from this weekends experience. You have a very good local team. Many of us in this area fight to get enough just to play. Doug has a better base to work with, thus can be a little more successful in the jump to 12U. The only way we can promote fastpitch in this area to be fully committed to our area and surrounding areas.
I would consider Milford, Middletown (Hawks are hosting a tourney there this year), Pastime Park, Portmouth, Columbus. Oh, of course the tourney in your back yard, Mt. Orab, Ogen Park. Cincy Static are in and will be good competition for your team along with the other teams.
Hope this helps. Good luck!
