I totally agree about the man labor to build it, as far as the other track options I don't think it would be an on track issue at eye level.......
We all know how they build things over there, the designer (forget his name at the moment) really took advantage of the space, and seems to be an excellent spectator track as well.
We'll see how it holds up after a big sandstorm or two
I also have to mention they did something right as far as the actual track surface, I can't count the times I saw where the track would start to fall apart in the middle of a race from it being a new surface....
