From having been at HD and Puke in recent times, I feel it's about time to let go of the nostalgia surrounding Puke. The Supertourers proved (to me at least) that HD , as a track is well capable of handling such cars, and the crowds would be well served. If the Supercars don't want to go there, I reckon it is their loss.
Of course it would be of financial benefit to HD, the spectators would be well served, and I believe the class would be a great show.
