In reply to Choss:
Bic lighters (the masculine sized ones, not the tinies). Reliable, easy to dry the flint by running the wheel over the trousers (with the new ones with the child-proof tab you need to remove the tab), strong spark, and the only ones that work well at altitude if you ever end up skinning up on top of Mont Blanc.
For extreme smoking with wind and rain, light up inside the rucksack or with your head inside your top and fire-lighting hand going in through the waist hole.
