just my opinion, but I really dislike hairpin 180 degree corners where you pivot the car around the end of a pipe. Corners with a real radius are much more fun because you can carry some speed. I just don't like "stop and go" tracks. I know it isn't possible to have a flowing track with limited amount of space.
