4.56's in the axles right now. It's slightly over geared from stock (speedo reads 75 to run 70 according to my GPS), but it's pretty good. 4.88's would probably be better as far as acceleration/power is concerned. You'd be winding it up pretty good on the highway though. GPS 70mph puts me around 2600rpm.
I know it's not exciting to watch. lol. Like you said though, it keeps things alive and you can really go some places if you know how to crawl. If I can't crawl it, I'll give it a good bump in double low 2nd gear. If it still doesn't come up, I'll pull rope. If it takes more than that, I need to change my setup somehow.
I've got more vids, just need to sort through and edit them.
You'd remember Rock House if you came up it. If you still have rear glass, you probably would've lost it on this trail (if you took the line we did). I've got video of Greg coming up it and bouncing his tube bed off a tree pretty good. I'll upload that one tonight.
I think Rock House was the furthest trail to the right. If you just climbed the Waterfall and took a 90* right turn, you would run into it (I think). The run started at the bottom of the hill though.
