6 wheel vs. 8 wheel WCD

A 6WD will generally need somewhat more ground clearance than an 8WD to cross the same obstacle. This is because there is more space in between the wheels to get a "high-center", where the obstacle hits the frame and stops progress. Those aren't exactly fun to get out of, and often need a hit from a partner.

Of course, this difference was hardly noticeable on the flat field we've had the last two years But it is a good point, if you go back and watch matches from 2010, almost everyone who could efficiently get over the bumps was an 8-wheel drive with some considerable clearance. (also note that I only know of one mecanum drivetrain that could get over the bumps in 2010.)

On a flat field, 6 and 8 wheel drives are almost exactly the same. 8 wheel drives do have the advantage when you look at the details, but the main difference between the two will be the quality of the driver.
