Man of Honour
Turkey and COTA are both pretty decent circuits and show that Tilke can actually design something that is interesting.
Istanbul I do really like (and India actually which was another Tilke) but other than that I've not been keen, I also preferred to "old" Nurburgring before they added in the new loop at the first corner (again Tilke)
Old Hockenheim too but that wasn't really his fault
