We use clx27's as everyday poles. They are plenty light enough to use all day long, and have that little bit of extra length to get over conservatories and extensions.
22 would be too short for 3 storey house, and we have loads of them, and extended/conservatories.
Regarding the clamp issue, I haven't owned a pole yet that hasn't required a clamp re-glueing, so to single out Gardiners poles as having the issues is not justified.
This brings me back to a point that has bothered me since starting...NOTHING is up to the job, NOTHING. We pay Snap-On money for Halfords tools.
