Thats the type of bot that is going to win king of the hill
Traction has about zero to do with surface area. This is even more true when on a completely flat and smooth surface. Remember, that traction is gained by friction. And, the formula for friction is F=uN where u is the frictional constant which is determined by the materials involved and N is the normal force. There's nothing in there about surface area. You do not need a lot of surface area to have good traction. In fact, it may actually be harmful (see one of the whitepapers about it).
