Round Rock's show is... well, I was fairly unimpressed. It honestly looks like they're playing Ninja the entire time. An entire movement of their show is just percussion, and their band doesn't seem to play a lot. Also, the colorguard seems a little weak.
Leander has a good show this year, as does Reagan. I think Leander has the potential to be fairly good; since UIL last week, I'm sure they've cleaned it and made it all shiny and pretty for Area.
