front rear or posi lock?

[soysauce]

Well i know this question has been asked before, but i have heard some conflicting things about this. Now that w2's are out i want to throw a locker in the XJ. I think i have settled on the aussie locker. I feel like it would be smarter for me to lock the front for 2 reasons, one: the d30 is a stronger axle than the d35. And two: it would make more sense to me to pull rather than to push. But i have heard that the d30's dont do well with lockers and that it is very common on a d30 to blow your whole front diff. Im also thinking about just doing a possi lock up front. What is your guys's input?
