Round Rock's getting known now for their uniforms. They're really nice, and a nice upgrade from our last ones. I'd go as far to say they're the best looking marching band uniforms ever apart from Phantom's >
Personally, my favorite is Phantom. I like their hornline best because of their full, rich, dark, phantom-y sound. Show execution may not be as great, but marching technique is consistent throuought the board.
