I too have to go it alone because of the roll bar rule. It makes learning the track difficult, Just take it easy and learn the track. Yes, you can go balls out down the straight, but why? Just bring it to a comfortable 120 or so and think about the next round.
Watch out for the corners at the end of the long Monticello straight, it is tricky and carrying too much speed into it can get you in trouble.
Get a "ride along" with an instructor, it is worth the time.
