Although it is more pricey each pole now comes with the following included in the price (unlike the last one) - choice of Super-Lite Brush, plastic gooseneck, hose and choice of fittings and a second end cap for use when removing sections.
If you want to use it at 25ft then simply slide off the largest section, fit the second end-cap and you have a 25ft pole that is about 3mm narrower than the last pole, weighs about 140g less than the last pole and is about 2" shorter when closed.
