rear end height High or low or inbetween.

I just go the dart down on wheels and and thinking about the height
I bought the wrong springs (6 leaf HD springs, my bad!) any way I put them on and then lowered it about 3 inches. I'm thinking I need it somewhere in between that 2 setups but can't decide. I know it'll drop a lot in the front when I get the motor and trans in. here's what they look like now in either the high or low setting.
so far I have 215/60 14's on the front(or will have after I fix the flat from sitting) and 275/60 14
on the rear. it's tight but I have more that 1/2in clearance to the wheel well lip and almost that much to the leaf spring in the lower position and with the 6 leafs it doesn't flex to much at all.

here's the high setup. a little high for me since the front's gonna go down with the engine/tranny weight

here's the lower setup. I like this one but it might go a touch higher. can't decide

I know it'll sag some after a while so I want to go a little higher than I think I want and let it settle down after use.
