nice thanks. I use the Denatured stuff, you can buy at box stores and REI.

What do you mean by fuel velocity? I use a White Box Stove (mod: wrapped kevlar twine around it to light faster). I get that its the vapor that ignites and when there is no pot on top it burns fairly weak. Place a pot or kettle on top and the pressure creates a very loud and powerful flame.

I do still use the provided windscreen.
