Starting a BB Duster project

Hi Andy, Just curious, since this car will see a lot of street use, in the categories of ride vs traction, what do you think of the Calvert system vs a set of Mopar Super Stock springs. Not from personal experience, but I have read the Calvert system was a little hash on the street. And to address the issue of the car sitting unlevel on the super stock springs, some use the same side for less or more arch / height.....also use the lighter weight 2800 lb to get the rear ride height lower.
