For residential ladders are 98% of the time the way to go.
The problem I have with double sided 16' is the weight. We have one and due to the extra weight it gets beat up very fast.
If you bought it of course your gonna try and treat it alot better, but the guys on the crew are gonna trash it. We call ours 'The Widow Maker'.
From my experiance I would skip the double sided its a pain. Invest in 2 single sided ladders. A 16' and either a 12 or 14'. So when you do hang that heavy chandelier you can have one guy on the big ladder and one on ther smaller.
My van has 4', 5', 8', 12', 16' double sided, and a 36' extemsion ladder.
