I always pick the retro kart whenever I can. It's just MK64 nostalgia, with the crappy shortcuts and the overpowered rubberband lol.That actually seems to be a decent combination. I always use the B-Dasher (isn't that the MK DS standard kart? I forget) with the slick/cyber slick tires with my light blue Shy Guy. I win almost every time. But yeah, as they said, don't use bikes. I loved them in MKWii but not MK8.
In MK7 I also pick Queen Bee for the lulz, I wish they had brought her back.
In MKWii I think the best bike was the Mach Bike. At least for the middle weight, otherwise it probably was that Bowserone for the fatasses.
