Got my new slx extremes today and gotta say so far I'm well impressed. Had a little play with them and put my swivels on (sorry Alex). I'll be trying them out proper tomorrow early on some NHS clinics. They are unbelievably light, the 18 with the extension so effectively a 22 ft pole is noticeably lighter than the mk2 18ft slx. They are so rigid as well a lot more than the slx range even the mk1.
The fast release carbon gooseneck is a brilliant idea, I can see me converting from swivels to the carbon gooseneck on commercial cleaning. The only thing is that the top clamp on the pole does the gooseneck so if you are already an slx user this will take a bit of getting used to as you'll constantly be pulling off the brush funny watching my Mrs try it out.
In the second picture you can see how they have done it. Not only have they used High modulas cf but the poles taper out at the top and bottom, so that weight is reduced. This means that you can't clamp the pole half way, only the top 4 inches or at the bottom. I wondered if this might be a problem but for the last few weeks have been using only full sections on my poles and have to say that on a 4 or 5 ft pole (section lengths) especially with a swivel I've had no issues at all. Well done Alex brilliant poles.
Simon.
