I think the overall consensus will be that the most versatile setup (assuming manual tranny) is as above, dual cases w/ 4.7s in rear case. That gives you options of 1x, 2.2x, 4.7x, or 10.3x. But also most expensive route (extra case + adapter + gearing etc).

With 200+ Billion electrical parts, the world most complicated machine is inside your own skull.

Question Reality.
