Ha ha, I remember we had so much trouble with that, until we switched to treads, but then we had even more problems with that! But I would definitely rather use unpowered omnis if we had the budget, cuz they don't change directions as easily from bumps. Also, casters cannot deal with uneven terrain, which is a little easier on omnis. My favorite type is mech, because it actually tank drives when you need it, and is much simpler.
