I have an old Gardiners SLX22 that i've had for so long I can't even remember when I bought it.
It has the original 'old' clamps etc. I also have the Xtreme 22 which I use every day and I am very happy with it.
I cleaned up my old SLX with Gardiners dry lube and Gardiners tape etc etc, to keep in the van as a spare.
Bloody good pole and I've had no problems with clamps etc (like others have).
I think the best pole to use is the Xtreme 22, (I have elbow problems)
BUT, the BEST VALUE pole is without doubt the Gardiners SLX 22.
