Great post, very informative.
I just wanted to add an observation of mine: I still think the Spark-Lite is THE best out there, I mean if they added a lanyard hole to it it would be perfect. <img src="images/graemlins/grin.gif" alt="" /> I also love my Zippo and Bic. Bic I carry because if it is submerged and dried it still works and it is storable, the Zippo because of the wide range of fuels and space to store spare flints. (both of which can still be used to spark after they are out of fuel) Those are my three favorites. On my keychains I carry BSA hotsparks because:
1. They have a hole
2. They are cheap
3. They are easy to get (my local scout store is within a few miles from my house, I can always run and get more).
4. It can throw a wicked spark

For matches I like the strike-anywhere kitchen matches with the heads dipped in candle wax. If they made "strike anywhere kitchen size Nato match style" matches they would be perfect. <img src="images/graemlins/frown.gif" alt="" />
Again, great info.
