I'll bite. Not in any order by the way.
Top 4: Marcus, Hebron, FloMo, CTJ
Middle 4: The Woodlands, Vandegrift, Reagan, Bowie
Bottom 4: Bell, Leander, Coppell, Duncanville.
I think that Vista Ridge also has a great chance to break up into the top 12 as well. UIL and BOA are just so different that it's still difficult at this point in the season to make any predictions. Also, a lot of bands can't really be compared yet. I haven't heard anything about Bell, Coppell, or Duncanville, so I have no clue what to do for that.
With Vandegrift, Leander, and Vista moving up to 6A this year I genuinely believe that UIL 6A has become one of, if not the hardest, marching band competition in the country. This year is gonna be crazy.
