After testing MANY different oils, IMHO, it is best to start with a 1000wt and go from there. If the car is stable and you need more rotation go with lighter oil... If you want to tame it down some, go heavier. We used to run 5000 in the Serpent gear diff, but that was with half the gears... I would say in really high traction with mod, you could be as high a 4000 - 5000.... talk about forward bite......
