I was under the impretion that we swithed to air to gain consistant velocity and to keep liquid CO2 out of the guns and freezing them up.
Jynx factor - this is actually a popular myth or urban legend... Co2 is in fact the most consistent, reliable and best source of propelant for a paintball marker. It's just that you earthlings have not yet learned to harness your energy to control it!
Anyway - back to this alternate reality...
I haven't got an air system... I've got an air bottle. Big difference!
As a result, i'm going to use it for Co2 until i sell it or get an air reg.
If i could afford it i would have an air system (see my sig).
