Tough call this, I've got/had both.
Extreme 22 lasted me 3 months when I snapped no2 section pushing a window to, I know I shouldn't have but was rushing.
Bob plum bought the sections off me, replaced the broken one and is happy with it. Now I'm back to the slx 22 and happy with it
I will buy another extreme but only to replace my slx35 not as my everyday pole.
Gerald Ash, you must like the whip of a glass fibre pole seriously, a carbon pole is much easier to work with.
