I know I hate calling off all of my chips with a medium pair. Against other players I might fold this. I made the call he showed K/4 off. Needless to say I was bounced out of the tournament on the bubble when a he completed his set of 4's on the river. It depends on what you want to do in a tournament just get in the money or win. I always want to win and never mind going out on the bubble, I want wins.
