The blind 3 at THill just takes once over to know you turn before the hill crest and your fine. Turn 5 isn't that bad either as your going so slow over the top (okay, I did wash the front out there once). Turn 9 is another once you go over it, it's easy to know where the line is. That's the only hard turns there. That and the pavement is so bad... it's like a 3rd world country track
The issue I had with THill is its not that much of a thinking track and the straights just don't do well for 250's.
I like Barber as it's tight, technical your always thinking. Sears Point (okay Infineon) is another track that can be a fun track. The track flows so well and there is a perfect mix of tight technical and long sweepers that is makes the track okay for both big and small bikes alike.
Now Jennings GP down in Florida is a fun track for a small bike. No actual elevation to speak of, but the track flows so well. That and it's a bike only track, so the pavement isn't messed up yet (Thunderhill running cars in 110 degress does wonders for screwing up pavement).
Not sure If I will be traveling out to Texas any time soon, just too far for a track day when I have more then a handful within 8 or so hours from home
