Ok - first thanks all for the replies - here are couple answers/additional things to keep in mind.
1) We like to keep our spot ops on headset at all times (see the thread i started a while ago about follow spot cues)
2) We used to have a lot of beltpacks but many of them have started to break (and the
theatre that we rent has refused to repair them) - so now, we have 4 or beltpacks + 1 wireless (we used to have like 3 wireless) - we generally put one on SL one on SR and then the two beltpacks for each follow spot on the catwalk. The wireless is either given to the director backstage (on shows where we don't have a lot of tech time and she wants to make sure we know whats going on) or to sound. This past show, though, the conductor wanted to be in communication with me so I had to give the rail (SL) the wireless and put the wired into the pit (with a phone instead of a headset) because there is no call light on the wireless.
3) We don't have any cue lights in the theatre - (i hate this so much)
I think thats it. Again, thanks for your replies & I look forward to others!
