Jim,
I know people who have removed front propshafts and having driven one like that, I have to say it handles better. there is debate by some that you are putting more load on the rear hub and bevel boxes, but having had a long experience of working on Ferrets, I say the wheel stations driving are under less load, due to no presence of wind up. Ferret hubs have a certain weakness in that the bolts and dowels securing the planet carrier, and thus hub, are know to shear, due to the stresses of wind-up.
It all depends on how you drive it, if you drive like a demon, then maybe stick to 4wd. Also if you envisage going off road at times then it would be embarrassing to get stuck.
There will be someone who has gone for 2wd and had a bevel box fail, saying that is proof they will not take the load, but I have seen many bevel box failures when driving all four wheels. Your choice!
