bags -vs- juice

Ok heres the deal i was about ot order my air ride in a week but i talked to someone who has the same sert-up on anohter monte, and they said it doesnt give much of a drop, i dont want that i wanna get my car as low as possible, with it still being able to drive daily, i've been looking into juice, cuz i know it will get me alot lower, but the problem is i dont know the 1st thing about juice, can you guys give me some pointers and kinda explain how it works?
