In winter with cold fingers or gloves the Bic/mini Bic can be a bit of a challenge and I find that at around 25f it needs to spend some time in the pocket to work.
So I use a Firesteel. For a while I have used one from Going Gear ( http://goinggear.com/index.php?main_page=index&cPath=4) cheap and produces much bigger blobs than the Light My Fire version.
In my last trip I could not find the GG version so I had the Light My Fire and managed to brake that (the rod broke from the orange holder)
Then I could not start the BIc so I borrowed the Light My Fire from my mate making sure to be a bit more gentle with it..
