Dasmond I have my first ever extreme a 25 still usable. Much older than the 22 possibly around 2010-11 but in all honesty it's only used about 1 hour a week and that's probably more than it's actually used and I'm just waiting for it too snap
I'm deciding what to purchase a 35 or another 25 or just move all jobs that require a 25 to my subcontractor and just stick to 22
Not sure yet
But my daughter is 19 in August and started when she was 16,the summer she left school and she's still using her 18 extreme but she only works 2days with me so will last till end year
I've worked out years ago what wears out the pole and it's using it downstairs on lower windows, the side ways cleaning action and many hold there pole to tight ( hence often the trigger finger, tennis elbow ) and it's that movement that puts so much twist through pole clamps and wears the carbon, IMHO
So I allow pole to twist through my grip and they don't wear as much
But if I was giving pole to staff or subcontractor, one which was more durable I'd give an 22 SLX as it will take more abuse but I can't comment on how it stands against the new style extreme
