Haha exactly. Did you work for Land Rover from 1999-03? Justin's video is very accurate of how TC is unable to achieve the level of traction that CDL + TC can. There's a reason people lock diffs, it's just works better.
By the way to respond to your earlier "overlanding" comment. A couple months ago I was at an event in Connecticut, halfway through a trail one of the drivers felt something odd. Only to find this under his truck:
He was driving an 01 I believe, but he was smart enough to install a CDL linkage. He was able to make it out of the trail, stay the rest of the rally, and drive hours home without a front driveshaft.
And are you completely forgetting about the three amigos? One of the biggest problems to plague the DII? If you're unlockable and TC fails because of dirt on your abs sensor what are you going to do? 1 wheel it out?
