I haven't gotten to drive it much so I didn't really try starting in 5th gear double low. I'm pretty sure I'll be trying it in Moab. The group I'm going with takes a ton of pictures and video so I should have some nice pictures of the trip!
I could easily start in 4th gear with my single 4.70 gears so with duals 5th should be a cake walk.
I'm sure you'll have time to play around, but if you need the muscle, you know 1st gear with that setup is the only way to get to 223:1 on the trail the other gear ratio's should be higher, so crawl low in first since your first gear ration is 3.93...just my opinion.
1st gear in high should be 3.93x1x1x5.29= 20.8:1
5th gear in double low should be 0.83x2.28x4.7x5.29= 47.1:1 so twice as low
5th gear in 4.70:1 should be 0.83x1x4.7x5.29= 20.6:1 so about the same as stock 1st
