Not Happy with 4.5/7 RQ, should I bag it?

[Bryantcm]

So I just finished a complete overhaul of the suspension on my 67 with a 4.5/7 drop with all the usual parts: spindles, KYB, c-notch, new wheels/tires, etc etc.

The end result is I'm really happy with the look, but the ride quality is just not acceptable. The rear is particularly harsh, I'm assuming due to the 5" drop springs.

So my question is this: Is air ride that much better for a quality and compliant ride? While I am budget minded, I'm not one to spend thousands and it not be "right." I'm considering making the change to a basic air ride kit with manual valves since I'm not really concerned about laying frame or playing with Air. Just set ride height and enjoy.

Any opinions on the difference in ride quality? Is it worth the effort?
