I'd say once everyone speaks up at the briefing what way they want it run would be good enough.
If its a half day one way and half the proper way or whatever, once its agreed on in the morn by everyone it shouldn't be a problem.
Even if they just run it the normal way Saturday and run the Prodrift course on a couple of practice days in the spring leading up to the new season so its fresh in ye're minds would make more sense?
