i
absolutely disagree in terms of the literal meaning of "to break = to crack, to break into pieces". Huieson balls. i'll talk about them in the pongbot thread: tl;dr Huieson balls are terrible balls per se, because yes they get way too easily perma-dented (as shown in Haito's photo), i.e. they are NOT hard balls ... but this feature is actually an incredible advantage in pongbots: Huieson balls doht crack in pongbots, nor do they get dented in pongbots.
the other alix balls, weixiun, are terrible though in pongbots. they doht get dented (because they ARE hard balls) but actually crack, i.e. break in pongbots. and more. i'll talk more about them in the pongbot thread soon, watch out!
