B series, Pt.1 the Busy B

Here is the First in a series of B tracks, Fast and Rewarding, tight and and painful if you go off, 17.36 Lap time so far.
  A word about kinks. Try to line up both sides of your track, but ALWAYS line up the White side of the gradient for best results. Try to keep it as realistic as possible, but notice you can often drive straight through a chicane or other style kinks.
  I put some in just to screw with people, to see if they take the fast line or not,YMMV

No perfect angles

More kinks
