Anyone try the progress coil springs? I have a big block and am thinking about it?

 
I had them in a car about 15 years ago. I did not like them. When you are traveling fast and the road gets bumpy, it can cause the car to feel like its going out of control as it will be undulating and bouncing all over the place. They are ok for cruising and their designed niche, but I like specific rate springs as they are predictable.

 
I had them on my '68 coupe when I first put in my 393w. I hated them. So then I swapped in a set of linear rate 620's. I am much happier now.
