Overload shocks on a Duster?

My front suspension has been done for a while and its time to clean up the rear end. I am putting in the energy suspension poly bushings and replacing the shocks to see how I like it before I consider things like panhards or watts links. I have the PST bars up front so was thinking about stiffer springs in the back in some manner. While looking at shocks I came across these from monroe :
58496 :: e-Catalog :: MONROE® SHOCKS & STRUTS
Instead of being an air-leveling shock they are a shock and lightweight coil-over unit.
Has anyone run these or something like them on their cars?
They seem like they could be a nice way to freshen up some old springs, or they could be a great way to ruin the handling of a good car.
What are your thoughts?
