I watched that Poker After Dark, and was suprised I could name all the players. Phil Ivy is no fun at a table. Quiet, moody, sucessful. Deadly.
Hellmouth was not obnoxious and almost a pleasure to watch. There are rumors he is like that most of the time.
Matisow at a table is fun, as would be Daniel.
I think I like watching Jennifer Tilly most.
My guess is that at that level, all the players are nearly equivalent, and it becomes style that wins or loses.
