It seems like everyone
makes the same transition. CO2 is a great starter when you aren't sure if you want to commit to the *ahem* hobby (or should I say lifestyle?
) of paintball but then you realise that an air system would enable you to stop complaining about your equipment (improving even firing a bit) and make you look like robbo (well without the warp).
So CO2 for value, then air for ease, but at a price.
Just from reading the forums here this seems to be the general gist of things, and I can tell you that liquid CO2 running into the gun will knacker your seals and make that marker a mite chilly, being as it is at about -50 degrees or so.
I do work with large amounts of liquid helium tho......
*grin* Shame the liquid is so cold, it would be terribly inefficient to run a thermal jacketed helium cannister on your marker, it takes a lot of lagging to soak up that -270 C odd temperature.
*chuckle*
