Jeremys,
Remind me of where you live and maybe I can help you out with meets.
USAPL allows bench shirts, but they have to be single ply Inzer's. I am not sure if Denim is allowed, or if it has to be poly, but I am almost positive it has to be Inzer.
You youngsters just stick with it, eat a lot, train smart and get plenty of sleep, you ar way ahead of the game by starting so early. I envy you all.
