I do agree the ARB is the way to go...and if you are doing one you might as well do both
However,The Aussie in the front has been very nice.Where some people were making three point turns the VX would still make it in a single.As far as a trade off in turning goes the only time I have noticed any real issues was in mud but with All Terrain tires it wouldn't make a difference if it was locked or not....it was still going to slide
Once the rear one shows itself it WILL be purchased and WILL be installed....after clicking on the E-brake in Moab it's time to go ahead and lock the rear too.
I myself couldn't be happier with the Aussie but to each his own...some may not like the feel and some may not like the hassle of dealing with hubs.
I do know if a SAS ever comes into the future it will have a selectable in it.I would look like Popeye after a week in Moab after turning 35's on that slick rock with a lunchbox in the front
