Just got my new slx 22 with extreme medium mixed brush.
First impressions, the brush weighs about a 1/4 of my old brush.
The pole its self feels about the same as my Harris so I wasn't too impressed with the weight.
But once built up I took it in the back garden and opened it up for a play with my upstairs windows.
I can't believe how much lighter and stiffer it feels than the Harris when extended.
Its fantastic I'm very impressed, can't wait to take out out and give it a go
