Holonomic drives sacrifice traction in the same direction mecanum drives do. Holonomic drives have just as little traction as a rubber wheel, in theory. In practice omni wheels don't have very much traction in any direction unless you double or triple them up. Combine that with a low friction well greased gearbox and you will realize the wheel wastes power scrubbing motion in the wrong directions with any holonomic system. I would not recommend one.
