Track #2 looks Fantastic!
MUCH more challenging course with some "You better know what they heck your doing" corners. Not as many "Oh well I can always just go off into the cow pasture" corners.
A lot of double apex turns.
There are even a few Gas well heads you'll need to avoid.
I would recommend novices stick to the regular track until they get significnant experience and there is a wide breath of knowledge about what to watch out for. Good Track video is going to be key to accerating the learning process.
