I guess you can try and get a little more aggressive in the later rounds. At some point you're just gonna have to get lucky...tha'ts the way tournments are. Maybe instead of inching your way down until you have nothing left and you need to double up 3 or 4 times...when you have a decent stack try making some moves and try to get lucky. Just a suggestion.
Other then that..not much you can do being card dead in a multi....I've noticed I do very, very well in tourneys where I don't have a major bad beat. If I go up against one..I'm usually screwed.
