Personally I think using omni wheels on the corners is a bad idea and I strongly advise against it. As a driver, whether on offence or defence, if I know that you have omni wheels on ur corners I will use them to my advantage. They may make your robt easy to turn... but that just makes my job a whole lot easier. i just tap ur corner and you spin like a top. I can pretty much push you where ever I want and you can't do much to stop me.
From past experience the "rocker" is the best method of 6wd. if you can keep your CG rather constant (like not moving from front to back alot) you probabilly wont even notice a rock. Just be sure to keep the friction down on your corner wheels (i.e. only use 1" wheels if using high traction tread). This will still allow you to turn easily but give you enough traction so if pushed you still maintain control.
IMO...
