closer settings

[dharmabums]

I have Rafael Soriano and George Sherrill in my bullpen (2009 $80M cap league). I have them both set in my pitcher prefs as setup (the rest of my bullpen is <$1M and not so dependable). I also have Soriano set as closer vs RH and Sherrill set as closer vs LH. Does this closer setting make sense? If I make them both "closer" then the first one listed gets used much more often than the second one listed. I would like to use their strengths, but does the setting I've used mean that I could lose them quickly in batter-pitcher matchups? Thanks for any advice you all can offer.
