Need help determining wheel size

[corndoggydogg]

I have been struggling with determining wheel size. There are a lot of good threads on the forum regarding this topic, but I haven't been able to find the exact answer to my question.

First off, I don't want to go with the slammed look. I want to keep my truck functional for hauling loads, but drop is slightly and fill the wheel wells with new wheels/tires. So I plan to put 2.5" drop spindles up front, and 2" drop shakles in back (keeping existing leaf springs as is--no flip kit).

Here are the scenarios that have been crossing my mind:
1) 17" or 18" wheels all around, same width all around.
2) 17" or 18" wheels all around, wider in back.
3) Staggered diameter, with wider in back: 17" front / 18" rear ; or 18" front 20" rear.

I have attached a photo of my truck. I would love to see some photos of your trucks and receive as much input as possible. And most importantly, which of the above options do you think would look the best?

Thanks in advance!
