What you need wayne is a pole with removable sections but still telescopic. don't know if the x-tel's do this but facelift poles do. So basicaly you only use the number of sections you need, add sections for higher jobs & take them off for normal use. I have a 44ft carbon facelift but use it at 24ft 95% of the time for all tops & bottoms, i only use my little pole twice a month now & this is only on 2 conservatories with very, very tight acsess.
A 24ft carbon facelift is just a dream to use & has a base section not much thicker than a broom handle. expensive? yes, quite, worth it? even more so, once used you'll wonder how you ever managed without it.
