I say always have ferrorod (or sparklite), matches, and tinder because what if some rug rat has to use my kit to start a fire?  Far-fetched, I know, but what if? But its still debateable, it depends on who is expected to use the kit and their skill at using what's in it.  Just my plugged-nickel's worth.
