See, I think the fuzzy memory of years past has led many of us to forget that back when an F70x14 was a cool tire, even those got booted for an L60x15, which significantly changes the rake of the vehicle, which has led many of us to believe that our cars sat better originally than they really ever did. Lets not forget that mother mopar NEVER speced a ride height for the rear of their cars, but did so explicitly for the front. This set up was also typically much taller in the nose than most modern enthusiast would find acceptable. I can post the factory reference if anyone cares to see, then challenge anyone to go verify their car against to see if they truly are set to a stock ride height, regardless of wheels/tires they use.
Personally, I've never had any trouble out of a set of MP XHD leaf springs. I've installed three sets in my personal cars, two in my brother's cars, and sold a dozen sets to customers who have had no complaints. Then again, I've done so knowing that they are not designed to lift the rear so much as control the axle. I also typically lower my cars even further to reduce the overall height as much as possible.
I also do not care for Espo springs, but I expect different attributes from my springs than most, so I realize that for the vast majority of car owners, Espo springs will easily and economically fit the bill for what they want to achieve, which is a raised ride height and a nice rake. Since this can be achieved in a variety of ways, then if it works for you, makes your car feel/look/ride better, than I'd say you made a good choice.
