As mentioned, the amount of air is critical. The normal pressure points of you butt should still rest right on the seat and the air cells should be just enough to fill the voids to spread the pressure out.
I don't remember which size I have on mine, I'd have to check in the morning, but I like it. One other thing I did was cut a 3/4" piece of foam to the shape of the airhawk. Then I tapered it from the full 3/4" in the front to nothing toward the back. This leveled out t he saddle some. I just put the foam shim inside the airhawk case, under the air cell.
You could also lower the pegs for more leg room if you haven't already.
