It's not objectionable. I'm solving a problem with constraints: how to go up the stick given I don't have anyone helping. Having someone winch you up in a bosuns chair does not satisfy this constraint. Sending oneself up in a bosuns chair is probably trickier than using one of these.
One
advice I did see was to first send a bosuns chair up to the location where work needs to be done, then hoist one of these ladders, then go up and get into the chair and do the work.
For me this length is a bit short, trying to figure out how to cover the remaining 5-7 feet (same constraint: I am always working solo).
