Ride quality expectations

[Napa69]

Hey guys- I have a related question to suspension set up. I just bought a 69 which has the Hotchkis 2 in lowering springs up front but on the rear the previous owner just dearched the leafs. It has QA1's with the rear being 12 way adjustable. The problem I have is the back of the car rides horrible. I know with lowering you sacrafice ride quality but it cant be this rough. I figured that the rear shocks were not adjusted properly so I have played with them which has helped but they seem to either still bottom out or end up too stiff. I like the stance and want to keep the ride height the same. Do you guys think the rear shocks are shot (about 4 years old) or do you think I need to replace the leafs with matching Hotchkis or DSE drop springs? I called QA1 and they recommended I start the adjustment at 4 and stiffen from there. 4 still bottoms out and anything over 6 is too stiff. I tested the bottoming out by putting zip ties on the shocks and after a short ride they were beat to hell...I'll try the white grease too...any sugestions on dialing it in?
Thanks for your thoughts

P.S. Vince, where you guys located? I am in Napa and might be interested in talking about having some work done like on your hompage.
