My only concern with these poles is their long term durability. I took a pair of brand new Gossamergear Lightrek 4 adjustables on the John Muir Trail this summer : one pole snapped after 110 mls, the other snapped just after finishing ( they both snapped in the lower section 1 1/2 ins below the upper part). I only weigh 126 lbs , but do put all that weight on the poles, especially going down rock steps. The first failure happened when I tripped getting onto a log and probably overloaded the pole, but hey, who doesn't stumble once in a hundred miles? The second went for no apparent reason, just had had enough I guess. (I mended the first with a short piece of tent pole that had sat in my first aid kit for years, and it lasted out the trip).
So, I would like to ask Will whether , after a summer of further use, he thinks the poles are strong enough?
PS. I have ordered some lengths of 11mm aluminium pole to insert into the lower sections of the Gossamergear poles, which will hopefully both repair them and make them stronger.
