nwh, the hose on the brodex must weigh 400g so if I use pvc instead I will save 200g, if I replace the gooseneck with a gardiner, I will save 400g, then another 200g with an ionics brush instead of a vikan, thats a total of 1kg, so the pole will weigh around 2.5kg, and its extremely stiff ( as stiff as the cf facelift 24ft, held both in space of a few minutes )

notice the weights of some equivalent poles
the official weight of my pole is 2,9kg without gooseneck and with brush and hose, I got the gooseneck free becuase the first pole they sent was defected. The vikan brushes weigh 450g and the hose is that reenforced stuff!
