Here's a mind boggler. A WDH will induce directional instability . Remember we are talking about true sway, not the tail wagging. This is a twisting motion. Say the when trailer lurches to the right, then the WDH is going to transfer that motion to the right corner of the TV, suddenly your TV is now pointing to the left. From experience,all blood in your hands gets squeezed out as you tighten your grip on the steering wheel.

Not quite right! It is not the WDH that is causing that. It is the normal reaction to the tow vehicle to the forces of the trailer on the ball. That would happen whether there was a WD hitch in use or not.
The use of a WD hitch will lessen the effect a bit however since it restores some of the lost weight on the front (think steering) axles of the truck resulting from hitching up the trailer. This allows the truck to steer somewhat normally instead of being light in the front.
The common use of a friction sway control will stiffen up the connection at the ball somewhat which will also help reduce the motion you describe.
