is it not better to have your employee to trad ground floor windows while you pole tops?rather than have 2 hose reels and 2 poles etc?then 400L would last you a day.no messing about going home at lunch etc.
i dont know but is having 2 wfps out of one small van that much quicker?ive never tried it.2 lots of hose going across roads etc?
This is what we do at the moment Daz, but he poles and I trad

When I get the 2nd setup, id only use it on are estate work, and roads where we have loads on the same estate/street.
Some very large properties we do it would pay to use 2 poles.
Theres still a load of work that would be quickest just to pole tops and trad bottoms, the same as we have work thats quicker just to get the ladder off.
Diffrent methods work for diffrent houses, and diffrent people.
We all work in diffrent ways, and you need to find whats works best for you.
