Which 3 of these receivers should I keep?

Devery Henderson, Roddy White, Bernard Berrian, Vincent Jackson. I can play 2 and have one on my bench which one should be left out? I was thinking Berrian but what if Ferotte starts lighting it up with him, plus he was injured a lil bit on Sunday. The other 3 of course haven't been putting out many points but hey this is what you get stuck with when you draft runningbacks and QB's first.
