If you do a PFD, you will not have to worry about DOLA cuz the account will no longer even be on your report anymore (assuming the CA follows through with the "delete" portion of the PFD, which they do not always do--get it in writing before you even consider the PFD).
While on the PFD subject, I have a question--when requesting a written PFD agreement, can you have them specify that the delete has to take place within a certain amount of time after the payment? I could picture some CA's not deleting the account and saying "well, we just haven't gotten to it yet" and then letting it drag out indefinitely if you do not have a date agreed upon in writing.
