Regarding the fresnel lense being the best firestarter for minimum carry - I wouldn't agree. I think a mini-bic, a match book of matches or even a BSA flint would be better. The limitations of the fresnel lense are too confining to make it a good main method of fire starting. It's true - it's probably the smallest and lightest, but it doesn't have the flexiblity of use the others have. Not so good if you want a fire on a cold, wet night for some reason, or if you need to light a candle at night.
