Kinda like ladders. I use the heck out of a 10' and a 16' orchard ladder, tying in sometimes to use the 16'. A very light-duty (200 pound rating) aluminum extension ladder is what I call "taking the stairs", again sometimes tied in. Can save a hundred or more feet of climbing per day while pruning, and all leg power.
Couple that with a power pruner, and I saved a lot of climbing the other day. 5 trees crowns' were interlocked, and they were were multi-trunk messes of conifers. Canopy raising them all meant climbing into each multiple times.
I don't prune much with a power pole saw, hard to control with precision in some situations, easy in others. Good for stubbing off the beginnings of some canopy raises, and some removals.
On many a day, neither pole tools or ladders come out, too.
