yeah man, saw that....way too soon. I don't know details on either of them, but it sucks. I was fortunate enough to see Slipknot waaay back in '98 (or was it '99)...at any rate, that was one of the few mosh pits that I wouldn't go into, back when I was going into mosh pits. Judging by the number of people who stumbled out bleeding, I made the right decision. Slayer? no problem.
