Minor quibble, but I think what you mean to say is "Therefore I'll act 
as if I believe". Covering your bets on something physical works; it 
doesn't often work in the metaphysical realm.

You can make propane more efficient in the same fashion. Instead of 
having just one line from your regulator to your jet (assuming a 
carburetor instead of a blower), you run one line to the jet with a ball 
valve (a quick lever shutoff valve) in it. In parallel with the ball 
valve, run a line with a needle valve in it. With the ball valve off and 
a warmed up forge, set the needle valve to the lowest flame your forge 
will run stably at. When you open the ball valve, the forge runs full 
blast. Close it and it stoppers down to minimum.

Hopefully that came through understandably; if not, we'll try again.
