I played around with it a bit when I got home from work. Looking closely at the saddles, they really aren't shaped that differently. I really don't get it. It's not the hardness against my sit bones, it's just my positioning that isn't comfortable. I played with the tilt, and the fore aft a bit. Since it actually seems the b17 rails are located a bit differently. Or to better put it, when in identical positions, the b17 will be longer towards the back than the team pro.

Sending it back in the morning.

Those fizik saddles are waaaay expensive. Too risky just to order one. Have to find a shop that sells them. But then again they probably won't be mounted on any bikes.
