For downstairs you may find the 1 metre section a tad too long, so you could cut say 10" off and still use the extension section. I often did this with the 30 metre- have a small ground floor top piece and often just whipped it for the bottoms leaving the rest of the pole assembled. No idea what a "unitec " is now as I am no longer trad. but there is also anothe topic chatting about glass fibre decorators poles, they are warmer to the touch but not sure about spares.
I think there is also a warm to touch ettore/ or winspray pole.
Fill your boots the world is your oyster.
