I would get a flint and magnesium stick. I have the firesteel and it works but I feel like the magnesium with flint and steel works consistently for me. With the fire steel I have a hard time getting the sparks to last long enough to ignite the tinder whereas with the magnesium I can get it to light almost immediately. You could also get a backpacking stove I have that one and it works really well and is super light and tiny. It just screws onto a butane can. I would also recommend something other than those mylar blankets. A wool blanket is a good alternative, much better than mylar, though I have heard that mylar in conjunction with wool works very well. Good luck!
