middle point between floor and ceiling if you are close to the front of the overhang. i don't think directional mics are going to help you that much since you are already losing a lot of waveform. if you can walk up and hear the preshow pa music and compare it to your spot, and it's much worse... shut off your machine/s, pack up mics, micstand, roll up wires, and put all of that stuff in the coat-check. sit back and smoke pot... or whatever.
