Backpacking stoves seem to have moved away from replacable plain (orange) rubber hose (like on full size double burner (car) camping stoves) but narrower: eg first epigas trangia gas, epigas alpine but now modern ones come with a stainless steel braided outer and crimped connections: is this that much better? could the braid not hide damage from view? if the braid unravels, aren't its strands going to possibly abrade the inner hose? would a high temp fabric braid be better? losing fairly simple user replacable tubing seems a pity.... NB as the thinner 3mm ID epigas style hose sounds hard to ghet, would full size 8mm ID hose waste too much gas when disconnected for backpackers remote stoves?
