While having a front locker is sexy, the practicalities of it are,
that you'd rarely use it unless you are offroading a lot.

I decided that for my usage patterns having a limited slip
differential was a better choice. I added the decoupler on a lark at
the last moment. But I figure, with the rears locked, the front
engaged, and a limited slip up front, I will have to be pretty
seriously mired, if my combo won't get me out. In which case....you
get a winch (still not yet in my arsenal, but probably will be by
next summer.)
