Before I die I would like to be known for the following pair of observations, gleaned from 35+ years of live concert recording:
[1] No microphone arrangement at a concert can ever be small or unobtrusive enough. Even if your mikes were the size of a single hydrogen atom, someone would still complain that they block the view.
[2] At the same time, even if you use a mike stand sixteen inches in diameter that glows a bright throbbing red, as soon as someone walks into it (ruining your recording), they will invariably blame you for not making your equipment visible enough, when they weren't looking where they were going.
In the 1970s I used to attach cards to my mike stands that said "WARNING: 600 Ohms." Believe it or not, I think it got me some respectful distance sometimes.
Also, omni and wide cardioid microphones are relatively immune to picking up physical shock, as compared with cardioid, supercardioid or figure-8 microphones. (When I say omni here I mean a true pressure transducer--not the "omni" setting of a dual-diaphragm, switchable-pattern microphone.)
