That's an interesting way of looking at it.

My oldest son Steve (a freshman in engineering school now) went with us the AZ regional, and noticed that 60 was doing very well with a very light robot. It does have a powerful 6wd (rocking) drivetrain, but didn't have all the weight that we normally associate with strong pushing bots. He's trying to convince 1726 to try a few matches without ramps or bumpers, to see if the added agility of a lightweight bot will be more advantageous than the pushing power of the full weight version. The difference would be about 25 lbs.

I was thinking about the rocking thing some more...in this years game, it looks to me like rocking is not much of a concern at all, as long as you are hanging tubes by dropping or hooking them onto the spider foot. And with the rack moving around sideways as much as it does, if you are scoring some other way, vertical rocking would be a very small concern.
