I too really dislike Vineta K. Primarily the long narrow tunnel. It feels extremely clastrophobic to me. Almost more technical than Chenghou, because I can't hold a great line unless I use the joystick as it has too many sweeping turns that don't work well with a full turn you get with the d-pad.

As far as rating the tracks, I definitely think that there is not too much change in difficulty on them. Each has it's tough sections.

Well, except Anulpha and Moa Therma, those play like wide open weapon fests. Especially Moa Therma. So many big areas that are open for weapon fire there.

From a technical standpoint I would rate Chenghou as the toughest track. To consistently hold a strong racing line requires lots of pitch control, airbraking, and side shifting. I think it's why I love it so much.
