Could use a closer...Soria or Matt Capps?

Currently in an extremely deep 16 team league. My closers are currently Billy Wagner and Chad Cordero...barf. Soria is actually out on the market and is enticing. However, I've seen reports from numerous websites that S. Torres is getting rocked & in possible danger of losing his spot to Capps very soon possibly. I'm leaning towards Capps b/c I think that once he's named the closer, it's his for the rest of the year. With Soria, while obviously better at the moment, he's more of a stopgap for Dotel once he gets back. Need some help, thanks.
