So little weight and space is involved in carrying "modern" materials, even redundant techniques (which most of use seem to prefer - typical is Bic lighter, matches in a waterproof case, and ferro rod or something equivalent) that it is a no brainer. Add in the greatly enhanced ability to start a fire in adverse conditions - the kind of situation when you really, really need a fire - and the decision becomes a super no brainer.

The primitive techniques are cool, and interesting, but they fall in the category of "parlor tricks," in my opinion.
