Daz, you have just let others change your mind for you.
I have a 22 slx and it does 99% of my work, including some 3rd story work, and windows over connies. i only get my 27clx out a couple of times a month.
The aqua dapter is great, bumper was unlucky, i have dropped mine loads and never broken.
With the closed lenght of the 25 slx, plus the Aqua dapter, you are looking at a long pole for everyday use, that is another reason why i went for the slx.
The auqa dapter is an expensive tap, but it is the best tap, the slx or supalite extreme poles are expensive poles, but they are the best poles, you get what you pay for.
you should have gone with you original setup idea.
