I'd wait it out if your are in a DMP. If payments were made on these debts recently then your SOL could have easily been reset. Outside of GWing paid accounts including CAs, there's not much else you can do unless you are willing to PIF. In other words, if you have cash in hand where you can send out a DV then a PFD then it would certainly be worth it. You need it to be removed. But also remember, the CAs don't have to accept a PFD thereby placing you in a situation where you may have to cough up the money to avoid being sued. Also, fighting it could place your DMP in jeopardy.
Paid or unpaid CAs are just as damaging. Doesn't matter if you owe $0 or $100,000, the damage is weighted the same score-wise. Under a manual review by a potential creditor, you'd look better with a $0 balance. The damage does lessen with time. But there are plenty of stories in here of people receiving 20-40-60-even 100 point bumps at the 7 yr mark.
