500lb Spring rates?

About to order new springs, I have no additional front weight on my double cab v6. I don't want the 600 lb springs to be too stiff. Anyone have expirience with 500lb springs?

 

im like 99% sure im running 590 and IMO they are way too soft. backstory though when i bought the truck research showed the springs at ~900lbs i was used to that but knew it was stiff. was told 590 would be good and i mean they are not horrible but its small things like when im off roading it allows more play with the body so i hit more. found this out on a trail where i never hit and after new suspension hit like no other. going down the fwy by my work there is a small lip that is just before a curve i bounce around like crazy when i used to just drive over it no problem . just what I have noticed. higher lbs can also be used to help think ahead so if your thinking about a front bumper get the coils now vs re buying coils

 

What length did you get your coils? 14?

 

OME 887: 400mm in height 590 pound spring rate mounted in 5100 with 5100 in the rear with an aal retaining the overload
