I personally recommend the rearward cross for lifted 4x4 vehicles, especially ones like ours that are hard to keep the alignment within spec due to the types of lifts we run.

The rearward cross is the best at mitigating tire wear associated with alignments that are at the edge of their spec range by putting each tire at every point on the vehicle. So say your right-front camber is a bit off, well with the rearward cross a tire will only see that position 25% of the time whereas if you go with the x-pattern it will be there 50% of the time.
