Circuit of the Americas 3

I have built now 5 Versions of COTA.
The first 2 are very bumpy in some corners, but have a realistic elevation in turn 1.
The last 3 were made with very soft corners and from different starting points, but the elevation in turn 1 is not satisfactory in either of those 3.
The problem is, that in the "Eifel"-theme (non-flat) there are only 2 starting points where you can place the Start/Finish line geographically correct, so that North is really North.
These 2 points are Starting Points 2 and 4, all the other 5 would start in a wrong direction!
However: you may have a look at all of them, just tell me which one you like most.
You can find them all here:
