Filter setup, Regulate or not?

[rustover]

Guys I've seen a lot of post where folks say to leave the regulator at the wall set at max and use a regulator at the gun. Here is a pic of my filter system:

I was planning on putting a regulator / gauge at the output of the desiccant filter, but now I'm wandering if I should. My compressor cycles at 90, and 135. This setup will only be used for spraying, most of the time the ball valve on the input side will be closed. Should I just regulate at the gun?

Thanks for the help. Russ

Barry told me to leave my stuff wide open and regulate at the gun. Hope this helps. Mitch
