I have vikan brushes on both mini poles. They are great for removing snail trails in rapid time and rinseing off the glass at that hight is not a problem.
On my 18' poles I use Gazas salmon brush. I like them because they are so light and they keep their shape very well, and I rinse with the brush on the glass most of the time.
I have 2 other 18' poles, one with a small vikan brush on which i only ever use on first cleans or cleaning cladding. The other 18' pole as a bigger vikan brush on it, thats great for cleaning big windows fast but it destroys my arms by having to hold it off the glass to rinse.
I have 2 x 24' poles one as a Gaza brush on which I use most of the time, weight and rinseing on the glass being the main reason. I have a vikan brush on the other but only use it on first cleans because its so HEAVY man.
I have a facelift brush on my 38' pole but I hate the thing, not the brush but the pole is to big for me and to bendy.
