my suggestion is to get a video of you using the polesaw while standing at the top of that ladder, and report back to us
I've actually been called out to jobs where the dude was doing exactly what you're asking about, and either got hurt or got his senses knocked back into himself, and decided to pay me to climb instead, cost him half a day waiting on me and if I recall, I charged him more than he bid the job for to begin with
ladders have their use, I have no issue setting one up to prune an ornamental with a silky saw, or get onto a roof to blow sawdust off, but in all honesty, I can think of maybe 2 jobs in 3 years where I put a ladder in the truck, and if I recall, only 1 of those we actually used it
