Go to http://www.carbonfibretubes.co.uk/standard-tubes/Scroll down the page to "Modular poles"The ones I use are CFTMOD50 and paid about £450 inc vat and delivery for 6 sections 40' total weight 3240 grams . Minimum order is 5 I think from memory. You then have to sort out the heads yourself as they only sell the poles and nothing else to do with guttervacs.If you want the lightest poles then Gardiner is the ones I would say to get Gutter-Lite High level Tapered Vacuum Poles https://www.grippatank.co.uk/gutter-lite-high-level-tapered-vacuum-polesbut are not cheap as a comparison 42' 7 sections works out at 2135 grams at £661.50plus 20% vat £793.80So the difference is that you would be paying a extra £343 to save 1105 grams in total weight. So the real question you need to ask yourself is it really worth it paying the extra money or not? I would say that unless you intend to do a lot of high work then probably not would be the answer.
