Here's what springs to mind on something like that if you have lots of good techs (and I mean good)... this is totally based on stuff I've don't in non-tech
theatre type competitions by the way:
If you want to have, say, 3 specials HL on the
catwalk, 5 specials HR
catwalk, 2 on the 1st
electric, and 4 on the 3rd
electric, then you have to divide it up. Have a 'chief' and 'crew' for EACH position. They don't talk to each other, help each other, ect. Completely separate groups. Then you have someone (LD) overseeing it all. That way you can get much more done in roughly the same amount of time. The trick to this though is-- PRACTICE. Get a neighboring school/
theatre/whatever to let you come in and practice this. Try it as many places as possible. If you can, bring the whole production, not just lighting.
I did a competition last year (not
theatre) where we had 4 pickup trucks full of gear. We had practiced setting up and tearing down in different places probably a dozen or more times. That way we were able to set up all of this stuff in a few hours with only FOUR people. Yes I know you don't have four hours... but you will have more people and less stuff.
