Whats a soft riding bag?

I am just wondering what you guys thought the softest riding bag was for the front of a S10 w/ shocks? Right now I run Firestone's up front without shocks and its alright. I was looking to lay the truck on 22s and wanted a bag that would get good lift and one that would ride smooth with or without a shock. I will be running the BTY arms so I dont think there will be any room anyways for a shock, right? Any help would be great.
