center rail is the place to be at the drunkbox. there have been threads about this, check the older team dc thread, and search for "the bridge" to see some of the debate about locations there.
tpoff seems to like running on the pole downstairs. the problem with the 'box, and the reason why hypers don't work great in there, is that the spot where you clamp is sort of in a dead-zone between the stage stacks and the cieling stacks.
you definitely don't want to run off center there, you are very close (<10 feet) to the mains and you don't want to run a stand because the air ducts above that center rail spot are noisy.
also, rokpunk from this board is one of the engineers at the funkbox, he can shed a lot of light on the intracacies of the place.
i'd rather have my fingernails ripped out than go tape DSO, but i'm sure we'll cross paths at the funkbox soon, i'm on the fence for the upcoming stanton moore/robert walters show, and am definite for the j.mascis show....
