Well the pros of air runner suspensions are a given but was wondering what the cons on the systems are?

From the air runner's website I see that a kit comes with:
2 Front Sleeved Struts
2 Rear Sleeved Struts
1 Tank (Standard or Pancake)
1 VIAIR 380C Chrome Comp
1 Pressure Switch
1 Wiring & Plumbing Pack

I don't see anything that is digital in the kit? Any digital readouts? Are the switches that come with the air runner's analog? If anyone can post a pic of an air runner kit out the box that would be great.

I've been doing some testing with the D2 air ride system combined with ridetech controllers and I'm tying to figure out all the cons that the air runners might have that this system might be able to overcome. Any feedback from you guys will really help.
