I have researched bastard packs abnd they seem like a good deal. Tomorrow is half price day at my local pick-and-pull and i know they have both s-10 and dakota springs. Does it matter which springs I get since they are both the same price? Does one flex better then the other? Anything special I need to know about them? Sorry for the million questions.

Btw i am going for about 4 in of lift to match a 3.5in RE superflex front.

 

I used MJ's on mine as they have the heavy duty overloads and the spring clamps bolted to the 3rd leaf.
