I'll be very interested to hear from you, especially if you are able to provide actual front axle weight before attaching trailer, after attaching trailer, and after engaging WDH.
This looks to be an interesting way to control sway. But purely from a leverage point of view (trigonometry, really), I do not see how this hitch can transfer any significant weight off of the rear axle to the front axle.
The chains seem to pull straight back, with no upward force. And it does not look like there is any means of adjusting the tilt of the head. But I have not been able to find a .pdf of the instructions to really read up on it. Only the info on their website, which does not go into details of how it works.
Please do follow up!
