I like working light. The majority of my work only requires an 18' pole. I currently only have a few jobs where I need the longer pole and it doesn't warrant me carrying around the extra weight of even the 22' pole for everything else just to do a few odd jobs that require it so I will always have at least two poles. Not sure yet whether I'll stick with the 27' pole. If I find over a period of months that I don't use one of the sections I might just convert it to a 22' and lose the weight that way.
fair play, we all work differently, personally I dont find the pole heavy at 27ft at all and thats after a full days work, I do still have the old heavy poles even have them stupd 4ft poles that are a waste of money (lesson learnt there).
I did used to change over poles but was not cost effective to do this, but I do a wide range in height so would spend more time changing over
