air shocks....to do or not to do

Did anyone mention the ride quality of the two types of shocks? If I recall correctly, air shocks are not a 'double acting' shock. I don't know how to explain it, but most shocks will dampen the travel in both directions. Air shocks constantly want to 'slam' back to the extended position, which has a bad effect on the ride quality.

I am basing this on 30 year old experience, so this may not be the case any longer.
