Best Autocross Tires?

[boxster or briefs]

Question for those who like to autocross or DE: What is a highly recommended tire for autocrossing/DE? I am looking for a good crossover tire between events, but to complicate matters more it needs to hold up a little for street use. I was thinking Falken Azenis vs Yokohama Advans. Here in AZ most people seem to be using Hoosiers or Ecstas but these are not practicle options for me since they need to hold up for street wear. Eventually I will have extra rims and can purchase the aforementioned tires, but until then I am looking for a good compromise instead of the Michelen Pilot Sports I have now. Anyone with any thoughts would be appreciated.
