Lamb of God and Killswitch killed it.
The crowd was lame for Testament though. The pits were dead for a good portion of the set, leaving room for the hardcore dancers to do their nonsense. I'm can put up with with hardcore dancers at hardcore shows, but seeing them in a Testament pit and not getting put on their asses was a damn shame.
Oh and what Chuck Billy was throwing out were mouthguards... I got myself one...hehe.
