lowering/tires/rims....Q? is anyone here running...?

[67 cst swb]

Ok, I know this subject is over talked about,... BUT...
Is anyone here running a 2.5" front drop, 4" or 5" rear drop...
(here's the key thing for me)
With a 255/70-15 or 235/75-15 tire up front & a 265/70-15 tire in the rear?
OR if your running big rims...
a 28.9" or 29" tall tire up front & a 29.6" or so tire out back?

I'm thinking of running this combo on my project truck. But am nervous about this exact combo. I've never ran such a small tire height difference...
I've always ran (personal rule) 1.5" to 2.5" stagger in suspension lowering (ie... 2.5"/4" or 2.5"/5") then (next personal rule) 1.5" stagger in tire sizes(example... 27.5" tire in front w/ 29" tire in rear) I've never ran the front to rear tires so close in size... I'm wondering if this exact combo would work visually for me...
I'm just hoping someone has this combo already, if not,... then something close to it...

Show me what you got, anything CLOSE might help...

And for my next personal opinion....
I think any tire shorter than about 27" tall (255/60-15) looks wrong on our trucks,... now before you start hating me... some of these big rim trucks flirt with this and pull it off, they look good. But, I guess what I'm saying is... I don't really like the small diameter tire look to much...
remember, just my opinion....
