Slicks will give a more progressive loss of traction.

With that said, you launch at 3,000 rpm on the street and you get a steady controled wheelspin and off you go. At the track, 3,000 rpm wont yield any wheelspin and you'll likely bog the engine for a slow start.

Launch it at 3,500 and let the clutch out too fast and your tires will be up in smoke.

As a baseline, I would try 3,500 and let the clutch out nice and controlled. The key is to not get too excited and let the clutch out too fast. ;-)
