as you know Dazmond i am a newbie with very much to learn. But 1 thing i learnt very quickly was not to get an xtel pole!!
I have got a 17 foot xtel with a vikan brush on, I hated it from the start, It bends like a banana and weighs quite a bit compared to my lovely 25 foot slx, maybe a lighter brush than a vikan would help, But I for one will never buy another. I use it on con roofs only now, but am almost considering ditching it for that and just using my slx (worried if the TFR will affect my brush though for window cleaning.
