Ok, thank you all for that.
I havent taken them yet, it'll have t wait till tomorrow as its dark now and my cheapy digital camera wont show anything if its not in daylight.
The poles I got were 18ft and 30 ft residential from Pure2o.
As a general guide, anything you can reach with 3.5m 2 section ladders can be reached with the 18ft pole. Anything you can reach with 3.5m 3 section ladders you can get to with the 30ft pole.
I'll get those pics as quick as possible.
I'll take one of the backpack, one of the trolley, any more?
