Air Hawk is the best I've found so far...but
I always feel a little detached from the machine when I'm riding on a day full of twisties. No matter how much or how little it is inflated, I feel "unsettled" when aggressively riding a challenging route. During every change of direction and acceleration or deceleration, I continue to shift in my seat even after the bike gets settled in the desired track. Kind of unnerving until you get used to it.
That said, I really love the comfort on those X-country days that are mostly motorways and tollways. Limited "sport bike" roads, i.e. long stretches of straight pavement, and endurance riding are when the Airhawk proves it's worth.
I agree the strap system needs improvement. I've even thought about removing some padding in my seat, under the upholstery, and putting the Airhawk in its place. Just haven't figured out the inflation scheme yet.
Good for long hauls, challenging on a twisty day.
Just my humble opinion.
