4.7's are the way to go. Even with dual cases I normally cruise around the trails in 4.7:1... in 3rd gear or better most of the time. I rarely use 2.28.. and 10.71 is used even less. Its so fricking low the thing will climb almost any obstacle in 5th gear.
From the looks of it I'm adding them to my "when I rebuild the transmission and transfer case" list. They do look like the way to go for 4LO though.
