Yes, practice is invaluable. I also have been experimenting lately with much of the survival gear I take. I sometimes carry a candle for heating a small shelter. It's amazing how much heat you can get in a semi-enclosed space.
However, for firestarting, I have carried one the various tinders & etc after my reading here @ETS.
Since I go camping so often, I have gone thru several different brands, but keep coming back to cotton balls in petroleum jelly. I have yet to be fireless with this method, and it seems to burn both hotter and longer-- thus starting a fire more quickly. A bit messier-- but the nearly "squeezed out" balls can be crammed into a small space-- like a section of the larger type of straw sometimes found at fast-food establishments-- and then the ends are hot-glued closed. Also these seem to work best, like many tinders, when they are pulled apart into many strands.
Please keep up the testing and let us know what you find!
& I learned this all on this website, so I can take no credit for the original ideas.
