I'd conceed that it may be hit or miss proposition with MP springs, but I think most of it is perception. Of all the complaints I've seen over the last ten years, only one actually had a set that had misaligned leaves adn as a resutl ended up with a bent main leaf. All the others said they were not happy with stance. I 've sold about a dozen sets to customs and so long as they all understood going into the purchase that these springs are desigend to control torque and not lift the car, I've only ever had one complaint. That complaint boiled down to someone who forgot to reset their pinion snubber after changing the springs. I've installed two sets on my brother's cars and three sets on my cars. I've not had any trouble with them at all. However, if they were bad and sat low from the begining, I didn't notice since I tend to drop all my cars down a considerable amount and typically will still use hangers and sliders to drop beyond stock.
