1. I would vote for daytona superspeedwy, and hsr.
I also think we should consider special stage route 5, would be great to have a night race, plus this track is so unused.
2. For race length, I say keep it the same.
Another idea that I have is to run a gp2 style twin race format, with the second race run in a reverse grid from the previous races finshing order. This race could be shorter and run at half points, and give a chance for someone else to win.
3. Endurance final is a great idea, maybe 2.5 hours
But let's do it on an easy track so everyone can keep up. It's not fun lapping people, and I'm sure it's not fun being lapped.
On a side issue, we're getting hit by a hurricane this weekend here in new York, so I hope I can make it but it's looking unlikely, they have already evacuated people near the coast, so I may have to leave Saturday night. I will try my best to make it though.
