OFFTOPIC:
Yep, I have not found anything (saddle, saddle cover, saddle pad) that rivals an AirHawk. There really is not any magic involved, it is just a simple fact that the air- filled cells can conform to any shape and spread out the support- which is exactly what they claim, their cushions eliminate 'hot spots' of pressure. And the shape of our.... er, butts, varies with clothing, even something like a wallet in a back pocket (for example: you are riding your new BMW home and your wallet is much, much thinner than it used to be.... an AirHawk will compensate automatically).
AirHawks are expensive as saddle cushions go, and they are not attractive IMO but they are one of the most functional parts of or on my bike. And I know I cannot spend more than an hour or a bit less riding on a Corbin without significant discomfort; I learned this lesson all over again once when my AirHawk sprung a leak while I was four hours from home :-( On long trips, I carry a spare AirHawk (seriously) because I know I could could not finish the ride without it.

I asked the same question in a pm. He said a airhawk makes any good seat better, especially on the 500 + mile days.
I would love to test ride one of those seats, minus the airhawk.
