NC and TN Super NIT's are next on the calendar. Not sure how many teams are playing specifically for the Elite 32 or just trying to play good competitive tournaments.
I do see several teams from GA in both of these (in 13U division), though.
The good part about going to them would be seeing a lot of different teams that you might not get to see here in GA.
For the 13U division, the MS SUPER NIT is the same weekend as Battle in the South. BITS will be tougher than ANY SUPER NIT. It is a monster. It will be the perfect view of what the Elite 32 will be like.
For the other age groups, I don't think it is a conflict.
