I can't say for tripod, as I use it so little that my old alu Manfrotto still works more then good enough for that little usage it gets, but for monpod, which I use "slightly" more, I'm pretty happy with Sirui. It's some Chinese stuff, but super cheap (about 100eur for superlight carbon, 6 section monopod that easily holds (with no wobbling or issues) 500/4 or 600/4 lens and 1dx... on step icy WC course
and works good, so honestly it's way better option then 6 or 7 times more expensive Gitzo. Not to mentions it folds nicely into super compact stick (thanks to 6 sections), that fits nicely into photo backpack. They have also whole bunch tripods for pretty good price. Considering this is under backcountry, I assume you will be carrying it into backcountry... so skip alu and go with carbon. It's more expensive, but believe me weight difference is worth the money.
