Anyone running toda spec-c on the street?????

I just got a set, havn't yet put em' in, and wanted to find out what you guys thought as far as drivability, and the supposed huge V-tec dip that they create, even with tunning???
I'm still able to trade them for a set of B's, but need to know soon, as I'm in process of building my motor.

Thanks,
Aj
