Thanks for the feedback guys.
Our league is not keeper, and the other unusual pitching category is that we use Saves+Holds instead of Saves. So closers do not have much value. Since we use W & QS, I've decided to essentially abandon SV+HD and stock up on starting pitching (no IP limit either). In additon to the pitchers I mentioned, I also have Halladay, Ubaldo, Brett Anderson, Danks, Romero, Pineda, and Wandy.
Right now I have no hitters on the bench, so I'd like to pick someone up - for today, D Wright is getting the day off, so I'll pick up someone who I may or may not keep long-term (probably Corey Hart, who just became available. Aaron Hill is also available).
