Awhile back I got hooked on Zippos from their great ad campaign. There are obvious advantages to Zippos, but I quickly became sour on them because of fuel evaporation and the associated odor. I couldn't keep one ready for use in a survival pack because of this problem. Therefore I went back to packing disposables with flint type spark ignition (because piazo rarely works about 5000 ft.).<br><br>
