Anyone think this will work

[snacob14]

I am still an airride noob to the fullest extent. After doing some searching and researching, I still don't know exactly the bag setup I want to go with. Something I just discovered are the paddle valve assemblies. This is my basic setup. 70 c20, 3 inch drop spindles in front, possibly step notch or notch in the rear to drop the truck level when aired down. I don't want to hop, I don't need to make a lot of noise, I just want to be able to drive it around and take it to shows. When I get to the show I want to drop it to the bump stops. When I pull up to the Sonic in town I want to be able to drop it to the stops. Can I do this reasonably with some paddle valves and 1/4 inch line. I seriously don't care if the thing takes .5 seconds to lift to ride height, I just want ride height to be adjustable.
Will these valves work. http://www.fbirides.com/product.asp?idno=260313 I would basically be creating a 4 path with 4 switches. If I can get away with a two path system I would do that two, I just worry about any body roll that may create if air passes from one side to the other.
I really would like some feedback. If I can put this together with a tank some air line, fittings and a compressor...then i'm ready to get started.
