But presumably you can split them and use 1, 2 or 3 sections as required thus making them easier to use.

Our Squeaky works like this; he has a set of triples; but usually I see him with only two sections on his car; meaning he isn't working any 2nd floor windows that day.
But personally, after borrowing a set of ladders to do some 2nd floor work - and not liking the extra height - I decided not to take on any 2nd floor jobs until I transferred to WFP.
The ladders are heavy; it's tough work; and if you fall, it's a long way down.
Even if you're 'anti-WFP', you could get a backpack set-up for around £500 which you could use for your difficult and dangerous accounts.
So, if possible and finances allow; consider an entry level WFP set up first.
I've taken on quite a few (small) 2nd floor jobs this year; and these pay well given the small amount of windows I do; easy too with a light Unger pole.
