Sub-9 is ALWAYS faster OUTSIDE of a bike. Super-9 is faster INSIDE of SOME bikes; e.g., inside of a bike with a lot of rear wheel cover and a VERY good seattube (aerodynamically) - P3, Shiv, Transition, Trek SC, etc. Sub-9 is faster in a stand, because what it does really well is keep the air attached. But what Super-9 does really well is the same as that picture showing how FC is a "Kamm-esque" design.
Airflow off the backside of a Super-9 is cleaner than it is off of a Sub-9 *IF THE AIR COMING ONTO THE WHEEL IS CLEAN.* So if the airflow coming onto the wheel comes on cleanly because of really good bike design, like it would for a bike with a lot of rear wheel cover and a really good leading edge on the seattube, then airflow off the "trailing edge" of the wheel becomes more important, and that's where Super-9 shines.
So if you run a *FRAME* where the leading edge is clean by virtue of frame design, then trailing edge aerodynamics becomes the trump card. In the case of my bike - a Transition (or a Shiv) - the Super9 will be the marginally faster wheel. But it's VERY dependent on the frame.
It's also important to consider that the Sub9 has significantly more vertical compliance than the Super9. I didn't perceive this to be an issue, but I'm also really light and put out a pretty solid w/kg, which means even less weight on the saddle, so I also think I'm less sensitive to it. I think both wheels handle very well, though I'm also sure I could tell you in a blind test which rear wheel I was riding due to the different compliance and handling characteristics of the wheels.
