I use a Slx 25 my new partner has just got a Clx 22.
My pole is a lot more rigid, but to be honest, I like how his has a bit of sway, springs back across the window as you scrub sideways.
He said it was a bit awkward at hight tho.
So just thought I would say go with the Sl if you can afford but the Cl in my opinion is a very good pole.
Ps, my slx seems colder than his, but may be where its warn.
