I've also got the TI box stove... IMHO and not having dealt with the cylinder yet... The box stove takes time and dexterity to screw together also. THe tiny screwdriver would be fumbling if I was hypo... if it was that bad, I"d start a fire outside before I did anything else if possible. I"ve been hypo to the point of walking the wrong way before and when I got my swamped waders off my socks had ice in them, I know what that does to you.
Under normal circumstances I don't see an issue with the cylinder, and would pack a few extra things with the box stove, after all if you loose a screw or two, you can't cut the others in half and make it work... though in my survival kit I do have some small wire that will be replaced with smaller leader wire at some point....
