Anyone settle a 2nd with BOA after filing?

Wondering how they are to deal with, and if they even try? If so, what kind of arrangement did you end up with? Did they take a certain % and then release the lien? Did it help if you were close to the 2nd having no equity? (Yes, I know if there is no equity I could go ch13, but am trying to consider all options, to include the "finality" and cleanliness of a ch7 as well.) Thanks.
