Also forgot to you on your other point. Sitting on top of the ladder. Yes that is another use, not just for wiring cans, but racks and other areas where you need a little extra height but will be there a while. I sometimes do it not due to fatigue, but to save my feet a bit of agony. It doesn't matter the kind of ladder I use anymore, they all hurt my feet if I stay on them too long, so its nice to have a little break here and there when I can. Sitting on the ladder is the same as sitting on the first few rungs, height wise, so you can get the boost and have a little less pain at the end of the day.
