My reasoning is that you'd only bring small rocks if you were afraid of hitting them yourself. i.e. you are not confident of manoeuver.
That is, my belief is that better players will be more likely to bring the larger asteroids.
1/ It would be nice if ListJuggler would record rock and obstacle choice as they are part of the list.
2/ Have people noticed a correlation between player skill and asteroid size? I am reasonably certain (but haven't recorded and counted) that I see more smaller rocks in the early rounds of swiss.
edit: What rocks or obstacles were brought at worlds?
