The clx and slx are excellent poles. I have both, but prefer the slx, for it is more rigid when at height than the clx, more precise and imo easier to work with, easier on the muscles than the clx. I have had both poles for 2yrs now and still going strong. The slx is used most often, with the clx used mainly on bungalows.
If your budget stretches to it, the slx is an excellent purchase. The 25slx will cover almost all your domestic work.
