Best Track Day Tire for Gen1?

What confuses me is that when the tire wears all the way down, rubber  
starts coming off and the cords come through.  That's usually in the  
10th-11th track day on the tire, 1 heat cycle per day.    I know this  
because I've ridden 2 sets of Pirellis down this far -- one because  
Wheel2Wheel screwed me and I ended up racing on an old set of shagged  
tires, and later on I did it just to see how linear the tear-down  
was.  The trackday provider had a fit when I rolled into the pits with  
the cords coming out of the tire.  Linear and predictable all the way  
down ;-)

Anyway, 10-11 heat cycles is all I've ever gotten out of the tires.   
Sometimes only 8 or 9 depending on how I abused them (20-lap solo  
endurance races, etc)

Given that I commute 36 miles each way, I'm thinking one week of  
commuting and the cords start coming out...?  There's cheap and then  
there's dead when the car behind you also going 80mph rolls over you :-(
