What rear springs to run?

Wondering what some of you guys are running for rear leaf springs? I was advised to check out Espo but don't have a clue on what to look or ask for. My car is mainly used for street driving (picture attached). I like the stance of the car now so I'm wondering if there's a spring that'll keep me close to where I'm at? One thing I do know is I don't want that *** end up in the air look. Thanks in advance..
