I reckon Gardiners may have beaten you to it skypole with their sl-x. But I still think their is a market for a 17-19ft strong - stiff - great clamps pole. I am quite annoyed with my xtels ( 17ft ) as the clamps are starting to spin after only 4 months!!!! apart from that it is a good pole to use. If you could build a 17-19ft pole that weighs less than 2kg, short sections, stiff and very tough clamps you would have a brilliant pole, Luke
