Hi all, I hope I'm posting this in the right place! I am looking for a ladder for focusing lights in our theater. We hope to have a lift in a couple of years, but it's not in the budget right now. I've seen theaters use the "trestle" style of wood ladder. I will be doing some of the focusing and I'm not terribly comfortable on that style and would prefer a-frame. It's been difficult to find a-frame ladders that are tall enough (18-21'). This one is fiberglass: Shop Werner 20' Fiberglass Twin-Step Ladder at Lowes.com It would probably work. The unfortunate part is that it is huge and we have very limited storage space. This one is aluminum: Little Giant Type 1A SkyScraper Telescoping Ladder 1121-ft., Model# 21 | Ladders + Stepstools | Northern Tool + Equipment We have actually been using a shorter version of this ladder. Should we avoid aluminum? The upside of this ladder is that it stores much better. What are my other options? Thanks!!!
