There isn't that much more traction with any of them. I don't know what roughtop would get using the vex method, but seeing as when you push sideways on a robot with omnis you don't get much normal force or friction (unless you are pinning, which is different), I would think they would work pretty well.

That is only in the direction of rotation, assuming movement is all in a straight line. Problem is because omnis have rollers on the wheels which makes them slip and slide and rotate, which makes it extremely easy to move an omni bot sideways, or rotate it from head-on.
