Thanks for the update. I have AGPs and I've been Very happy with them. However the locking mechanism is far from stellar.
Over the course of a year and maybe 50 trail days it has become increasingly difficult to 'lock' the poles after adjusting the length. More often than not I end up separating the sections and hand-tightening the plug, then, reassembling with a 'righty-tighty' motion, otherwise the pole just spins and doesn't tighten the plug.
I do clean the poles regularly but it seems to be more of a variable interior diameter issue. I'm still learning.
I've learned, for instance, to be very careful in lubricating the threaded shaft. (I do this keep the thread friction less than that between the carbon on the expander plug.) As a cyclist I have plenty of 'T9'chain lube laying around. Unfortunately the carrier in the 'T9' dissolved/softened whatever the expander plug is made of. No amount of force could move the bonded plug. I now use a pure oil.
And my hope was that GG had newer, better, more robust approach. Darn.
All that aside, I still love 'em and when they die, I'll order another set, rubber expander plugs and all.
