I have the 143 toupe and the airone.
I got the airone first and it felt pretty nice. It's only later on longer rides that I feel some pressure/pain in the center region. At the end of a century, I have 3 pressure points.
Then I got the toupe. It's kind of painful for the first few minutes at first having all the weight on the 2 sit bones. At the end of a century, only the sit bone area hurts, which I think is better than my airone.
