I have always thought the SM420 plus stock transfer rocks in FJ40's. The approximately 75:1 is the sweet spot for the Rubicon. But last year I did Fordyce creek for the first time, and honestly, lower gears would have been nice.While 300:1 might be overkill, 120:1 would be OK. It is very nice to go slow with the motor in it's sweet spot around 1800 RPM. I found myself having to lug the motor down to 400 rpm and that was too fast.
I think that an FJ40 at 120:1 would be perfect, so an h41 with Orion would let you do whatever you want. An SM420 with Orion is very low, but OK.

So will you have an Orion for this years trip?
