anyone run drag radials

I had them on a car that was 90% street driven/raced and 10% track,when you drive them on the steet for a while they will get a bit harder and not pick up stuff quite so bad but with a mild burnout they are soft again.When I sold the car I had around 20-30 passes at the track and around 2k street miles (and not real easy ones) and they were about 70% so they can last a while.They did hook awesome on the street,had to roll out a little but then it went.
