Thanks Phaedreus, Doug and Brangdon. Very good review and info. I do use Tinder Quick in most of my kits when I have them on hand. I much prefer them to the Coghlans fire tabs. I'll be ordering some fire cards. I've also been looking at the little fire starters made by Zippo, they appear to be across between afire card and a tinder quick. And it looks as if they would fit nicely in the nooks and crannies of a PSK. One thing I used to do was use business card stock, print signals, morse and other tips on them then saturate with hot wax, making an information sheet and a source of tinder. Hence my inquiry if they could be written on. I'll have to update my information and print some more of them.
