Too many good NFL Fantasy WR's. Which should i start week 7?

Too many good WR's, having trouble narrowing it to 3 for week 7. Here are my options, Greg Jennings, who is playing a weak Browns DEF but has been an overall disappointment beside 1 great game. Number 2 is Sidney Rice who although is playing the steelers has looked better and better and is becoming Brett's go-to guy. Number 3 is Steve Smith of the Giants who has been impressive this season and is playing a fairly weak Cardinals secondary, but has gone cold as of late. Finally Vincent Jackson who has been solid all year and is playing a terrible Chiefs D. Please help and whoever convinces me will get the "Best Answer" nod...
