You couldn't have said it better. This is just like the hoists that I mentioned earlier- great for putting up new equipment and using moving lights (no worries about bringing equipment through a crawlspace, or hanging something worth more than $1000 while you run the risk of dropping it 30-50 feet), but a pain to aim and focus anything (observe, lower, do some dance to appease your respective greater power while it's lowering, adjust fixture with only a slight clue of how your change is going to appear, raise, repeat). Thank god that the custodial staff have let me use the Genie lift as long as my supervisor's on site. Not to mention that our over-stage battens are dead hung, and that the classic cherry picker is scarier than climbing a rather thin utility pole during a hurricane. Sadly, whoever planned the rigging didn't take into account that the vertical pipes on the walls were going right next to seats, too far away from the isle that stretches across the auditorium for the Genie to safely reach, and right over a slope. We're just lucky that I was able to borrow my dad's extending Werner ladder (which just hardly reached at its longest state, and had to have a chunk of a 2x4 under it to keep it level), I swear, everybody on the technical crew will lay a curse on anybody that touches those lights. So yes, access is everything. Any apparatus or rigging that will grant easy(er) access to fixtures and mounted objects will be greatly appreciated by any school (and some professionals too).
