Just wondering what is the best set up air dog or fass ? and which system is the best for my set up and best vendor to go with thx much appreciated

 

We use air dog at the shop that does my work. Haven't had any issues with them. As far as I understand u don't need on on a 12v untill u get up into higher hp levels than what ur sig says. If I'm wrong let me know that's just what I understand from my reading
