Well what do you think Dazmond ... got yours yet?
sorry to jump in on this chris
I got a 40 just a week ago
very happy with it in the main, as its replaced an hxtel I recently sold.
Bought mine with an xtreme standard brush and a qr resi neck with a long neck attachment - makes deep sills and changing angles easy. even been using it on ground floors.
However I think you are right, when used at 45 degrees fully extended to clean velux its only slightly less bendy than my hxtel was, granted it is lighter though.
Never used a superlight modular but do think they would be more suitable for solar panel cleaning especially as there are no clamps to catch on roof line, tiles or guttering.
Very happy with my set up now of two poles, clx 27 for bulk of my work and when I need to be a bit heavy handed and the supermax 40 for the higher or tricky stuff.
