For my air shifter, I've been getting the bottles filled by my local "paintball dealer" (usually around 800 psi). When the pressure gets down to around 600 psi, I get it re-charged. It's very cheap to fill (<$3.00) but my concern is the time (my dealer is 15+ miles away). Also, what if the pressure gets below 600 psi during an event?

My question is...how low can I go (min. psi) without affecting the quality of the shifts?

Thanks for your help,
