The Bill Liebowitz Classic

I am thinking of entering the BLT in 2010. I noticed on the website there are 2 1a categories. Whats the difference between the rookie and freestyle categories? Also are there age divisions?

Rookie is for people who are not as experienced. The other FS division is for normal pros and such. No age divisions, and BLC is not for a loooooong time.

Sorry for the thread jack, but does anybody know the location and date?
