First off, well done. I march with Short University's band. We have some fun choreography, not just the traditional formations people think of when they hear the phrase "marching band". These guys get points for having a little extra flair, exceptional cleanliness, and keeping the geek factor of being in a high school band to an all time low. There's a reason they rack up state titles!
Secondly, my inner brass instrument craftsman is praying that the bands in my neck of the woods start introducing choreography like this. Can you imagine how many dents, dings, and folds we would be removing from these horns?! I'll just say I could pay for a Martin Committee pretty dang quick ;)
