optimal pressure for air bags?

[Ackattack]

I have my airbag setup installed, but I haven't driven the truck.

Where should I set my air pressure, just where at the height that looks good, or should I set it based on a particular pressure. I guess it may also depend on the weight of the vehicles.

So I guess, what pressure do you run at.

Also, when I was messing with it, it seemed like there was a fairly narrow band in pressure between full up and full down.
