for 30 feet up i use a carbonfibre fishing pole i bought 2nd hand off ebay ,used with WAGTAIL flipper 12incher modified exactly as on WAGGAS great videos .
the very last section of pole is a 5 foot fibreglass section of fish pole ,i use this as its less flexy than c,f ,it has a Wagtail Pole Cap glued onto its end . inside this very last section i slid a couple of small section of pole of about 18 inches long,.glued these in to reinforce that tip end section .
I use a regular pulex 3 parter pole for windows above conservatrys,with the modded wagtail.
those videos that Wagga has made of his modded wagtails are truly worth their weight in goLD
