Well, i went ahead and ordered a viair kit with a 2.5 gal tank. It's got a viair 450c compressor, which has a lower CFM than the ARB compressors, but I'm hoping the tank makes up for that. The York on the other hand puts out a massive amount of air compared to either electric compressor.

We'll see how the viair works. I may still someday upgrade the compressor itself, the rest of the kit should be compatible with any compressor. I'll be sure to report back once i've got it installed and get some use out of it.
