im 6ft 2in and still cant reach all downstairs windows on some of my round!
for most work it is easier,faster and better to WFP all windows but trad still comes in handy for tight space work or certain areas where you dont want to leave water lying around like certain inside porches,doorways etc.
i always have a pouch on my belt with a few cloths in and its easy to add my boab and a bottle on a belt if needed for some trad work.
for instance i have some jobs where i have to climb on very large flat roof extensions and its much easier to trad the windows above and of course inside windows!
certain commercial jobs also are easier using trad methods rather than dragging hose around.
use both by all means depending on the job but overall WFP is better and faster!!
