IIRC 2008 Trackballs were 10lbs a piece. Granted, there were no human players that year (robocoaches instead) but I do recall bystanders getting git by them every so often during gameplay.

IMHO the soccer balls in 2010 were more dangerous... they are lighter but also can be kicked pretty hard and unlike foam balls, they do not give when they hit. Just ask anybody who has been the wrong end of a drill kick in a soccer game (I've been twice).
