considering Chevy, Cadillac, SMS, Audi, and mercedes all use Eaton superchargers, it makes it pretty clear who the oems prefer since they are concerned with longevity of parts and quality

Touche teacher. It seems like the new TVS rotors are ?hybriding? toward a screw design. That illustration from the OP from KB's website made the differences a lot clearer though. Still, I wonder how much of a difference there is between the current screws and newer TVS-style. Who's going to do a shootout ?...
