Yeah, I'll do that -- try DIN or ORTF. Never have used either one.
Height -- I was only up about 6 feet, and the staff tried to run me out because people behind were complaining. So I suggested higher, and he said no -- so I suggested lower, and he said okay. So most of the show I was running about the same height as my head, as I was sitting in a folding chair.
Couldn't tell any difference in brightness between the two heights, or it was too subtle to pick it out.
