Timbo,
Have been to Parken in 2003&4, on both occasions sat in the upper tier of home straight. I would say that it is probably the steepest stand I have ever encountered, with the result that the view, with one possible exception is excellent, you are high but not too far back so as to lose any atmosphere- you just need an oxygen tank for the long climb up there !
The one exception I mentioned is the tv gantry which is lowered from the roof. In 2003 it must have been set high because I didn't notice it obstructing anyones view. Last year however, it was set much lower and interfered with the view of the back straight racing. To avoid it this year, I had planned to sit in the upper tier on the back straight but as you have discovered, these seats aren't released yet!
Enjoy it !
