So, while the compressed N2 may work, you get a lot of gas in very little space with the CO2..
That's correct. If you look at a CO2 tank with a pressure regulator, you would see the tank at around 800PSI for what seems like forever (as you slowly draw down the liquid level). Once the pressure starts to drop, then the liquid is gone.
Other tanks (nitrogen, helium, etc) don't do this. They start at around 3000PSI and gradually drop as you start using the gas.
