WR Dilemma. Who do i start this week between Larry Fitzgerald, Torry Holt, Javon Walker, and Derrick Mason?

Usually this would be a no-brainer but Fitzgerald is questionable and doesn't play til 4p. Line-up deadline is 1p. Holt might have Brock Berlin throwing to him and he's outdoors. Javon Walker has been injured all year and it doesn't seem like he's up to speed yet. Derrick Mason, well, at least I get a point every 2 receptions. Waiver pickings are slim with the top 3 guys being Battle, Currey, and Porter. This is a playoff game so obviously I need points more than usual. HELP!!!!!
