I never trust a Bic. I always trust matches first.
Bics stay pressurized for a long time. I always trust them, even in the cold, you simply warm them up a bit with your bare hands. I do the opposite you seem to do : I never trust matches (actually, I never carry them or use them in my kits).
I rely on the Bic, and I also have a firesteel in my wilderness PSK. Oh, and I have cotton+vaseline balls... <img src="/images/graemlins/cool.gif" alt="" />
I hate matches, basically. <img src="/images/graemlins/blush.gif" alt="" />
