I'll keep it simple. Whatever option provides for the most track time is what I prefer. Otherwise it just becomes another race weekend.

If the IT Fest is to be a crown jewel in the world of IT racing, it's gotta be Big, and Big includes maximum track time. LeMans wouldn't be LeMans with less than 24 hours, Indy would not be Indy with less than 500 miles. Bathhurst would not be Bathhurst with less than a 1,000K. The IT Fest should do justice to its billing and offer more than the piddling 80-85 minutes of track time usually offered at a typical two-day regional.
