Curious to what you decide. I'm going through the same motions.
Right now I'm leaning to the OX Locker in front and leaving the rear stock...for now. Eventualy putting True Trac in rear. My number one choice would be the the Ox in rear and True Trac in front, but with auto locking hubs it can't be done with out intalling manual hubs($$$). Of course I'm looking for it to very streetable at the same time go anywhere off road rig
