See: FRC494 in 2006.
This gives less fishtailing than two omnis on one end, similar stability to a 4WD with all traction wheels, and easier turning than said 4WD all-traction.

To verify my understanding before I do an analysis - are you advising four wheels, with traction wheels on one diagonal and omnis on the other diagonal?
And oh, yes - what was the aspect ratio (track to wheelbase ratio) of that robot? Where was the CoG? Well, now I've got a nice problem to work on in the evenings as I travel this week, If I actually have any spare time.
