If you want a factory Smooth Soarer Ride, go Factory Struts and Springs, I've never found any Aftermarket Springs to be same as factory they are all 20% Stiffer at least, Go factory struts too.
If you don't want to make it handle more sporty go a set of BC Coilovers instead of just strut and spring combo that way you can adjust it as you like, Best Value for Money. The good thing about BC's is you can get custom spring rates if you ask for it and they can go softer than what other coilovers offer.
I'd reckon a good thing is to get a $14/$15 Safety/Suspension check at Pedders that way you can find out which ball joints and bushes are worn, and you would be surprised the difference it makes. My Last Soarer had lots of wear in different areas once I fixed it all with new parts handling and steering improved a lot.
