If you're talking about what I think you are, see Team 60's 2005 robot.
They cut their wedgetop so that the elongated side of the diamond was facing forward. I imagine they did it more for better wear characteristics than for better traction.
It takes a heck of a wide sheet to be able to do that though. Looking at McMaster's site, they only sell 18" width wedgetop, which isn't even enough to go around a 6" wheel.
