ill chime in this time.........
putting the overload on bottom will only give support to the main leaf so it doesnt "wrap". the main leaf will still have some arch to it because it is designed for that.
putting the overload on top will force the main leaf to straighten out and "de-arch" it. running the overload will give you the desired look you want.
heres what i ran for years as a teenager and again once i got back into a static truck before i bagged this one.....put the overload on top for a few months to de-arch the main leaf. then swap it to the bottom for support and you will be good to go. dont do anything over a 3" block either. that should get you to the frame laying on your rearend and be as low as you can go without a notch.
