SiuLun's Levels were the worst for my ranking, and I realized that I had not played them too much. So I am trying to play them well now, like they are new levels. That is very wise. I can't be too specific in choosing levels; I play it because I have a low ranking, can get a medal, or can easily beat my time. The Golds here were bonuses almost too easy; I wouldn't mind just taking forth place, since I am still making great progress in the Time Trial without the medals.
