Which Catcher should I pick up?

I need a replacement Catcher for Chris Iannetta who has been really slumping lately. Which free agent catcher should I pick up. Remember its a replacement for a week maybe 2 until iannetta comes back to his usual form so I need a guy who is doing good right now and will be consistent. Here are some top choices: Gerald Laird, Koyie Hill, Ivan Rodriguez, Pablo Sandoval, Ramon Hernandez, and Ramon Castro (filling in as the mets starting catcher while Schneider is on the DL). Which one do you think is going to give me the most points now?
