Are you talking about the WWBA July 7-14? If so, that is the biggest PG tourney for 16u when it comes to the amount of teams and the quality of teams. I wouldn't consider going there with no less than 10 pitchers and at least 6 of those being PO's. Most good teams you see there will have 20+ players. You will probably not be very competitive with pitchers throwing in the low to mid 70"s. You will see a lot of mid to high 80's. Unless you have a bunch of D1 hitters and fielders, you will probably not have much fun.
I would recommend going to the BCS National in Ft Meyers. It's July 17-23, has a lot of teams that play, but not near the level of competition as Georgia. Just my .02. Goodluck!
