In response to several comments and questions regarding my reasoning for my dislike for 6WD and tread designs as a climber... Understand I'm not suggesting that they cannot climb. Of coarse they both can be extremely effective on inclines. But their MAIN advantages are massive weight distribution on unstable surfaces (tanks with treads in sand) and maintaining contact with extremely unpredictable terrain (rovers) when used with a suspension system.

So, my original post was under the heading "Basics"... and I was not considering anything with a suspension a basic design. In a basic (kit-bot) configuration the 6WD and tread option give you the same see-saw effect as you crest the peak of this games "bump". Not exactly the picture of stability. Toss in a reasonably high CG (needed for clearance in a static system) and the likelihood that your weight distribution will be biased in one direction to some extent, and well, I'm not interested. Two points in contact are by definition more stable…

We tested this out this evening as well (on a kitbot rolling chassis) and that's all I needed to see! Throw it together and see for yourself. Good luck.
