Thanks for all the feedback, guys.
Some quick, directed questions.
1) If i taped from the same location, but narrowed the angle between the mics, I'd presumably pick up more high-end on the recording, as well as narrowing the stereo image. Any other benefits/drawbacks?
2) If, from the same location, I angled the mics upward towards the PA, would I benefit at all? I imagine I'd get more high-end, as the high-end is more on-axis, and less of the inane chatter of drunken sorority girls. Would the stereo image be affected at all?
Thanks again.
