Well, I can tell you from some experience if you're on a slick slightly cambered road and one rear wheel is spinning, all locking the rear diff will do is spin both wheels and put you in a ditch!
Just a mile from my house there is a steep grade with the road tilted to one side. When the road gets slick, it takes some fine dancing to keep straight with a locked or posi rear. Back off the throttle and you lose momentum, the hill is steep and options are few. I believe that I did better with an open rear because I could stay on the throttle and take advantage of any small spots of better traction rather than missing them with an on-off technique.
