I believe it would fill a gap. I'd have no use for a 24' pole. I like the idea for the odd one that might ask me, however as an every day pole a 24 footer would be very under used and I'd have a load of extra pole hose at my feet all the time as I use a trigger for flow control.
I currently use an Unger HiFlo 17ft pole which does all my work but I would still like a lghter pole.
