actually...that is good advice!
I was thinking of keeping up the performance idea in all the changes I'm planning to make, so yes, i think i will use valves on each corner!
it's kinda along the line of; "if I'm already at the point of spending big money on the complete airride suspension, i better do it right the first time and add some more hardware now I'm at it!"

valves at each corner...good point! didn't think of that!
