I believe VexPro's ratings are conservative, because I know several of the engineers there and trust their design skills. However, based on their construction, the AM HD wheels seemed like a safer choice. We did not know in advance how hard we would be working that chassis.

All right, those are all good points. With it being a demo bot, you won't always being driving it on the soft carpet surface, so it makes sense that you would want to have the stronger wheel.
