I the Wii Wheel! It takes some getting used to, but I think it works very well. Yeah, it's a little corny but it controls just right: it's not too sensitive and it's doesn't require you to over-exaggerate a turn or anything like that. The only thing that sucks about using the Wii Wheel over the GCN controller is that you have to use batteries. Also, if you go back and play Double Dash!! or or any other previous Mario Kart game, you might find yourself moving the controller around to drive instead of using the analog stick or d-pad.

Also, cool idea for the leaderboard, Sonic! A lot of work on your part, but cool nonetheless.
