I agree to an extent, but this is niether Indy, or Champ Car – I think everybody agrees that the less classes / more consolidated everything is, the better race day is as an experiance.
I don’t know wether heavy / light is the way to go – I think a close look at the difference in times would be in order, but yeah – combining classes, I think, is a good move.
I still think qualifing on practice day (Saturday) is still something to look at, while maintaining time Sunday morning to get in at least one good practice session before racing begins.
just my opinion,
Gary
