IMO, it's kinda the same as with the rear. There are situations where alot of AD is good, and situations where it's VERY bad. I've seen a couple of rigs roll themselves over with AD. Example - in reverse, the AD becomes AS in the front, and the front lifts up... If you have a single radius arm setup up front, then it'll lift only one side of the rig... If you are off camber so that side is unloaded, it'll flop itself sideways when you hit the gas... Am I making sense?? Anyways, it depends on what link config you're gonna use as well. Radius arms have their upsides and downsides. I kinda like the reversed wishbone 4 link, where the lowers converge in front of the Tcase, and the uppers are parallel. All depends on what you can fit under your rig, and blah blah blah...
