I have been considering the Airborne for some time, and spent several hours the other day searching and looking at videos. I never thought of the effect it would have on towing stability.
I have been reading these forums since before the Sidewinder came out and have been watching threads on Sidewinder. There was a lot of talk when the first came out where members thought there would be a lot of stress in the wrong place, etc. but I yet to see one thread to that effect and I believe that there are trailer mfgs that have them standard equipment or options.
I recently put one on my fifth but have only towed 40 miles with it so not much I can say about it except if you didn't know it was there, you wouldn't know it was there.
I believe that the stability of a fifth wheel comes from the weight it puts on the rear wheels which the sidewinder doesn't change. Possibly at high speed very abrupt and sharp turns there may be a difference but not much. The very little driving I did in and out of traffic, I couldn't tell any difference.
I was sure that I was going to get the superglide, but the sidewinder seemed to me to be a much simpler answer to the problem.
Per the sidewinder manual, it raises the front 4".
