The All Cup Tour's fun because it compiles all of the tracks into one challenge that is more difficult to win.
Favourite track is DK Mountain, because of its numerous curves and angles that allow me to generate a power slide.
I don't really have a most annoying track, but if I had to choose, it would be Rainbow Road. Too long, IMO....
If you see me posting, it's because I've been asked to. Which I guess would mean I'm taking requests.
