They're using the Aerolab Tech sensor now and although I haven't seen the sensor itself yet, I've been told that the data quality others have been getting out of it is good. I'll have to reserve judgement until I see the data myself but Chris and Jon sell wheels, not tires, so the rolling resistance component was sort of a side issue, not their main goal. They're trying to figure out how to design a wheel that will go with a fast tire so they want to know what a fast tire is. This is a long way of saying that until I see the data (or get a sensor myself) I would look at general trends but not exact differences between tires.
