My records indicate that I used mostly lightweight characters, usually Toad and Koopa Troopa, in light vehicles (Toad's Kart the most common, but the.. green shelled kart.. is a close second).
Waluigi and Toad is in there a few times, in the Yoshi kart.
On a side note: it appears I was once trying to get a perfect score in the All Cup Tour, but the one for Mirror Special Cup isn't perfect. I want to rectify that, but don't have time now. AAAaaahhhh!!!!!
