My favorite combo is a 350, TH350, and 3.07 gears. I've run a bunch of different ones, but for me, this is the one I always am most satisfied with.

For me, it's a lot about economics too though. A 3.07 rear is usually cheaper to buy than a 3.73 (they are in more demand it seems), and a TH350 is way cheaper than a 700R4 is.
