I have the Werner multifunction ladders. In terms of failure rates, I would think the trail lawyers appropriately punish anyone who makes a defective ladder pretty quickly. I believe my ladders are 17 and 26 feet. Both are solidly built with the emphasis on solid.
Pros:
Can do all kinds of stuff, A frame, scaffold, extension ladder.
Wide base, this is nice.
Easy to transport, can be about 1/4 of its total length.
East to store
Cons:
Heavy as hell.
Nearly impossible to fully extend.
Your up 25 feet on a ladder.
I would consider myself retired from ladder work these days. Not that im too old for it, it is just hard and dangerous and not worth it. I still use them for time to time, but to get to the roof of a second story building this is not the right tool. I mean it can in a pinch but it takes all my strength and honestly is super dangerous to extend all the way. a 32 foot extension ladder is easier to handle. However has more limited uses and is hard to transport and store.
Mainly I think you need to find a ladder guy on CL. This is what I do. They have the right ladders to do the job. Find one of them online and they will get you sorted out and you wont be dead from falling off a ladder.
