Tosh can i ask you a Question?
I will.
You have a choice of using a Harris pole for your work or your clx. Which do you use?
Harris! Why? I prefer the smooth action rather than the ridges. I only use my 27 foot CLX for three story work, and I'll only use it on the windows I have too, I then swop it for my SLX.
You see, you can't decide your opinion is the only one that counts, because a lot of this stuff is subjective, not objective. Ronnie uses his Harris pole when it's windy, because he likes a heavier pole in this sort of weather conditions.
I also prefer 'twisty clamps' to side opening ones, because I use an external pole hose; I prefer working that way. Twisty clamps don't get opened like side opening ones when your external pole hose knocks them open.
I find external pole hose quicker to work with, and I have tried different combinations (internal pole hose and aquadapter, for example).
And really, for £15, even if there's any doubt in anyone's mind about the Harris, they're still better off trying one and if they don't like it, then that's fine also; it's only £15 and not £200 wasted.
But seriously, I'd prefer a Harris to a 18 foot CLX; but I prefer an SLX to all of them.
