You guys all have much more experience than I will ever have and it has been very informative reviewing you posts. If I were to invest in a ladder I would either borrow or rent one to use to see if you feel comfortable with it. My experience starts goes back to a 6' wood step ladder that I had purchased 40 years ago. The thing is built like a tank. When on a solid secure floor I have no problem breaking all the rules and stand on the very top without feeling uncomfortable. But the darned thing is heavy.
So I bought a Warner type #1, 250# 6' since I weight 225# and have regretted it ever since. It should ha just as well went with a 1A. I feel uncomfortable standing on the 2 step from the top limitation. The ladder is too squirmy.
I borrowed an aluminum 32' a while back that was fantastic in that it had rungs that were flat on the top which made it very comfortable to stand on. As long as it was set up on a stable surface it felt very secure to climb and work from. I was never afraid that a strong wind would blow it over. It was easy to extend and retract but a pain in the butt to lift into place by myself. If you think about the physics a 32' is 16' closed. On half of 16 is 8' which would be the balance point. Then you have to be very tall to have an 8' reach. So you try to walk up a 16' long item if you aren't able to set it against something when you have less than an 8' reach can be quite challenging. I would consider a 24 or 28' in you can't justify a 32'.
I realize that my experience is very limited but it is of my opinion that ladders are very personal and asking for opinions is an extremely good start. But they are costly and buying one that you end up regretting can be a waist of you money. It may be best to just rent a ladder that you may use infrequently. You may find a better place tp spend your money rather than on something that sits around a lot.
Again, I highly recommend that you borrow, rent, or lease one first and then decide which one you are most comfortable with.
Incidentally, it is to be noted that of the fatalities listed does that mean that 7200v should be avoided
? Also, being injured for fatally injured by a call from a ladder may be attributed to electrocution aluminum ladder or not. A fiberglass ladder just eliminates that as a possible current path.
