I ran a 90 2/6, band went off at 2:00, came back and played till 2:56 or so on the tape, mild stress. Next night ran till 2:04, I swapped a freshie just in case in one of the decks. Played till 2:56 again, but I'm told they blow through the 3 hour mark routinely. Interestingly, the light guy asked me about running 120 meter tape, and was not aware of the potential (certainty) of problems. I supplied a box of 90's because they were running out.
