what type of hose runs through the center of a telescopic pole ? is this classed as minibore or micro bore or something totally diffrent ?

its normally a 6mm ID 11mm OD pvc braided hose, Minibore size, but not as flexible. You can get it off ebay, £9.99 for 30mtrs.

the clear (non braided) hose is normally 6mm ID and 9mm OD (1.5mm wall thickness) although I bought some 5mm ID hose from Altec, much nicer stuff.
