I always include THREE sources of fire starting: butane lighter, a sparker, and matches, and those are presented in my order of preference.

At this time my preferred lighter is the Solo Candle Lighter because it is extendable, which makes it much easier to use when lighting tinder and gas stoves.

For a sparker I tend to carry both the Magfire Pro and a SparkLite. I prefer using the Magfire since it has lots more lights on it, but have to admit that the SparkLite is easier to use. Since the SparkLite is so tiny I can carry it too.

For matches I carry REI waterproof matches in a extended K&M Aluminum matchcase .
