hey lee,
i was in the drumline in high school. this one time in band camp (no, really, it actually happened... but without the flutes) our instructor had a quasi-professional audio guy come in and tape us. i wasn't paying all that much attention to his setup(it was a LONG time ago), but i was on bass drum, and he put us in the middle with one of each of our two quads to the left and right and the snares and cymbals in front of us. if memory serves, he used an XY configuration. also, we were in our band room when he taped us, so i'm sure the shape of the room and the sound baffling helped because the recording turned out pretty good. anyway, if you want to discuss it further, i'd be happy to help.
