Clxs are perfectly good poles.do the job perfect.i do agree they are a bit whippy at 27ft but for a few windows here and there they are perfectly ok.
I have a superlite pole now that is a pleasure at 40ft.cleaned a large 4 story hotel on monday and was a true pleasure.
i had a slx40 and thought how heavy it was at height and whippy too at 40ft which was the reason for the superlight modular.
i use a clx22 mainly and is a great pole for 95% of my donestic work.
