YES, you have the right idea, the facelift pole's sections are removable, it takes about 2 seconds to remove them
. So i would advise you go for the bigger pole to start with then you'll always have the extra height when needed. I have the 44ft carbon but only use 4x sections (24ft) most of the time. A lot of guys with facelift poles use them in this way. it also means that if you break/damage or wear out a section, it can just be replaced, any section. also, you can add to the pole in future if you take on any higher work.
