There are some simple ways to alleviate many of the drawbacks of Co2. An 
anti-syphon tube in your bottle will stop your gun sucking liquid Co2 but 
it needs to be set up correctly according to how the bottle is fixed in the 
tank. This will stop your gun freezing in all but the coldest weather. The 
addition of a remote hose between the tank and the gun will also help a 
lot. As for burst valves blowing, I've had one go in almost 30 years of 
playing paintball and that was caused by leaving it in the footwell of the 
car with the heater blowing hot air on it. It filled the car with fizzy 
vapour while I was doing 70 on the M56. The solution is not to leave your 
bottles in full sunlight or in the stream of hot air from your cars heater. 
If the burst disc does blow, they are pennies to replace and can be done 
easily in the field with the right size spanner.
