Found this video doing a comparison. They don't show a "both" option, and while one of the guys is from Equal-I-zer and can be forgiven for being biased, it is a pretty straightforward test.
That's a good video showing the difference between WDH and air bags. It's pretty amazing to think that airbags can actually contribute to overloading the rear axle rather than offloading it.

Agreed. I had no idea they would contribute to weight coming OFF the front wheels.
I've toyed with the idea of airbags, but always shy away because I'm concerned about reducing the efficacy of my WDH and also because I'm too lazy to have to go through the whole set up process again.
