I just had breakfast so here I am doing the forum rounds to see if there is anything new...
Yes TT sells "substitute" poles , the one for the Contrail is $6 , about 2 oz.9under "extras")
Not my cup of tea because it is a fixed length and not as strong as a trekking pole but it is light and cheap.
Easy to add strength to it by strapping a stick on it.
