Since then I've learned to use my ferro rod properly, carry twice the matches, and make sure that my cottonballs aren't soaked and are made from 100% cotton. I've also learned to carry fresh chemical hand warmers in my kit, because even when you have multiple ways to make a fire, it's really hard to do so when your fingers have gone numb!
All's fair in survival! No such thing as cheating.
I would suggest adding a few ESBIT tablets to your kit as well. They're very small (the 4gram ones are about the size of a peice of Dentyne chewing gun), waterproof and basically "immortal" as far as shelf life goes. They burn long and hot and can be scraped and lit with a ferro rod as well as with open flame.
As you say, redundancy!
