Mansfield has a spot too, I'm thinking, although I haven't seen there show this year.
As for class champions, I'm aiming for:
2A: Cisco/Holliday Toss-up
3A: There's only one.. haha.
4A: Total Toss-up to me.
5A: Hebron, even though Cooper was great a few years back.
EDIT: Yeah, I just looked at the results of BOA Arlington, and Flower Mound 4th, that's great.
Those tiny bands have a lot to put out there, they're up against 8 5A bands. Ouch.
