As NXTGeek noted, we use a 4 Wheel West Coast Drive. Six wheel drive improves agility because the robot pivots on the center wheel, so only two wheels are in contact with the ground at any one time. When we were originally designing Daisy Thunder we looked at doing a 6 wheel drive. However, when we settled on the robot's length (21.5") we found that the outer wheels would be about 17.5" apart, which is less than what it is when we do a long 6 wheel drive. With the outer wheels being 17.5" apart, the wheel base (center wheel to outer wheel) would have been 8.75". At this point we were worried about the robot being difficult to control and decided to stick to a 4 wheel drive.
