In reply to G4WTF:
I had a similar problem when I first used a roach pole in strong winds. I thought I was going to have to struggle back down the fells with an extended pole !
I found that if my hands / pole were cold and wet it made life very difficult so invested in some non-slip gripper gloves.
These did pretty well. However, I still had a few occasions where I struggled as one of my wrists is not very strong.
A couple of weeks ago in Aldi they were doing some DIY gripper gloves in a pack of three for £2-99. They are black and grey. These gloves are absolutley brilliant. The whole palm area is realy sticky. So far I have not failed once to retract the pole using these so now keep a pair in my rucksack specifically for this task.
Hope that helps.
