I think those Ressel trees indicate a January/February trip, so wasn't on that one (pity)
I was on this one...
Overall I am thinking to bite the bullet and go for 12s. Where necessary I'll just find a way to haul but also keep the option of going single cylinder on easier dives.
Why is it that with everything in life I always find a more difficult way of doing it (and not intentionally)
Warmbac 200m tacklesack takes two 12s or 15s nicely. No tacklesack is ever nice to carry with heavy weights though.
In Spain we were carrying 4 steel 7L cylinders several hours cross country up and down mountains. We used army bergens abd it was about as comfortable as you can reasonably expect it to be.
