Some Couglans tinder, (best compromise between bulk & burn time) wrapped in clingfilm might be a useful addition.

Bless you fellow convert to Coghlan's emergency Tinder!  <img src="/images/graemlins/cool.gif" alt="" />
I discovered something today.  <img src="/images/graemlins/shocked.gif" alt="" />  I rinsed off my ferro rod; because I carry it in my pocket.  I wondered if it would work when it was wet; I assumed it would.  It would not spark.  I just got wet gunk on my scraper.  After a few scrapes it would spark, but not at first.  So, if you are cold and wet, your ferro rod may not work until it is dried off or scrapped dry.
