Drag Radials vs Slicks

If your buying a pure race tire then a slick would be my choice the whole way. Things may have changed since the last time I was looking at slicks but the only benefit for the drag radials was you could "legally" drive to the track. I put legally in quotes because the tires would fall inspection after a few miles on the road hence the tread wear rating of 0 on the Drs I bought a few years ago.
