No insight here, either, though as I've mentioned I'm going to stick with the devil I know in the OEM pads. Since you drive the car every day, if I were you my priorities would be same or better performance, low noise, low dust, longer life, in that order. I think the Metalmasters are probably the best tradeoff given those criteria, but as you've probably noticed everyone says they are bad on the track. The easiest answer is, as Nate suggests, to get some Hawk HP+ pads for the days when you do driving schools; I'm sure the MMs would work fine on the autox circuit.
Let me know when you're changing them out, as I'd like to swing by and observe/assist.
