what are the downfalls in using co2?

[2.0]

CO2 is in liquid form when compressed, and gas when it expands. When firing rapidly, CO2 might not expand fast enough (depends on the ambient temperature, tank setup, marker setup and position of the tank), so liquid CO2 could enter the marker and damage some internals like the o-rings by freezing them (liquid CO2 is at about -60 degrees centigrade).

This can be avoided by either having good knowledge of CO2 management and a proper marker and tank setup (if the marker is designed for use with CO2 anyway, some aren't) or high pressure air (or nitrogen) which remains gaseous under pressure.

you're almost right.

liquid co2 gets into the marker and all expands, giving a massive burst or air pressure. This will blow out anything that is meant to handle only low pressure. Even on markers that can take co2 just fine you experience a velocity spike, which is equally as dangerous.

That too. But still, there's ways to handle and even prevent it to a certain degree.

I'm with both of them, but 2.0 is right the bad effects of CO2 can be negated by having the proper setup. I have a Smart Parts Vibe and I run CO2 because i play woods ball and I get far more shoots out of a tank. I also run it because the Vibe the Sp-1 and the Eos have the Max-Flo R Regulator with a special valve that vents the air when it spikes.
