Has anyone ever used a double CO2 regulator on a single keg system? I currently have a single keg, kegerator and am looking to replace the regulator. I have room to expand so I was thinking of getting a double regulator just in case I ever add another tap. Am I going to lose too much gas out of the second regulator if I only have one tank hooked up? Should I just buy a single regulator and not worry about the double until I upgrade or should I just buy the upgraded regulator now. What are everybody's thoughts? Thanks.

Buy the double and cap off the end to ensure you don't get any leaks. Or if it has a valve at the end just make sure the regulator is all the way to zero and close the valve.
