Well I forgot to mention in combination with the driver.

Make sure your frame is solid. I've heard from teams that have had problems with mecanums functioning properly with even the slightest wobble in the frame. If you use the kit metal, I'd recommend gussets and steel pop rivets instead of the hardware they offer.
Especially with the 6" wheels, the plates can dig into the carpet and prevent strafing and turning. Make sure there isn't any wobble in your wheels!

Actually, a flexible frame helps keep all the wheels on the floor. If it's too rigid, any deviation from a perfectly flat surface will let one wheel lose traction and control will suffer badly.

What you really want to do is control weight distribution. Try to make each wheel carry the same amount of weight. That will make it a lot easier to keep the wheels spinning the way you want them too.
