My post above was legit, no sarcasm. This has made me think a little.
If manufacturers tuned there regs so there able to accept a large range difference for input pressure, there must be a point somewhere in between for optimal pressure. Im assuming this optimal pressure would be somewhere between 600-650 psi ?
So if you used a mid-pressure of 650psi output from your air tank feeding the inline reg, would that not theorectically make the inline reg, in turn make the marker more consistant in delivery/charge of air ?
