Weight balance?

For various reasons, current draw being one of them, our '00 bot used a 6 wheel drive. In this setup, all 6 wheels are powered, where the middle two wheels are set about a quarter of an inch lower then the 4 corner wheels. This allowed us good climbing on the ramp (the primary reason for the 6 wheels) but also reduced scrubbing drastically when turning.
An excellent idea...

OOC, Were the wheels evenly spaced, or was the center pair nearer to one end? How was weight distributed across the wheel pairs? Did your robot rock back and forth between the outer sets of wheels when you reversed, and then run on the "back" (outer) pair each way?
