How to get the most bang for my HPA?

[Recon by Fire]

I am supposed to play paintball at an upcoming event with my boss and several clients in a few weeks. The problem is that the crappy field they are going to has NOTHING but CO2! So whatever I come with in my tank is all I have to play on that day. So how can I increase the efficiency?

I will of course have as full of tank as possible. My input pressure right now is at 1000 psi, so I guess I will need to crank this down. How low can I go and still get good performance from my X? Reactivity starts at 850 psi? Suggestions on where to set it for gas saving good performance (not necessarily reactive)?

Lower your input a bit. Use the short Lx spring and the shortest freak tip you have.

(makeing sure your running the biggest carrier that doesnt leak for lx would help too)
