I'm not a local but been there a few times.
I assume you mean with the AMA races in Aug, so that would be the north course. Front straight is fast and kink right over a rise, kinda blind but real easy to get used to. Heavy braking into turn one but the turn is wide and long so you can carry decent speed into it. Turn 2 and 3 are fast and wide. Turn 4 is tight but a very late apex sets up 5 and 6 nicely. Out of 5 into the snake, which is quick flick right and left and down the back straight, pick a letter on bridge to aim at to help you. Then uphill after the back straight it heavy braking the rocket up the hill, flick it back and forth all the way to the top of rollercoaster, this is my favorite part. Going down the rollercoaster is great, nice down hills turn. with a right turn at the bottom, you can carry a ton of speed through it and it sets up your speed for the front straight.
You'll see all once you get out there. Hope this helps and good luck.
