best leaf springs for smooth ride

Looking to replace the ss springs on my duster, all street driven car really looking for the best leaf springs for ride quality not launch but a spring that will soak up the major bumps in the road, as I have gotten older the ss springs did serve a purpose but now im looking for a smoother ride quality.i have been told the xhd mopar springs but just seeing the
xhd makes me think it will ride hard and not soak up the Wisconsin big *** pot holes we have around here. Hope to find someone with real world experience in this change out -thanks Steve
