I still don't like using the wheel, although I haven't given it much of a chance. I find the Nunchuk the best option, for me, so far. GameCube would be the best apart from having to use the D-pad for tricks.
I'm just trying to work my way through all the cups. 50cc is slow and rather boring. Haven't had much of a chance to play through 100cc and 150cc.
Need to get some online games under my belt though.
