only falure point would be the lines, and if properly installed, how many lines have you seen bust. now compare that to compresser leaks, leaderhose swivels breaking, or temporary valve failure due to debris. puttin em on the tank takes out all the failure points except the bag(cant fix that), bag fittings(cant fix those either). and the lines. basically, i just hate finding valves in random places around the truck. also, putting the valves near the bag adds another leak point in your fitting setup, but whatever i'm rambling now...
