My belief is that we should go immediately after the souls. If they are on their way to their birthplace, we would want to be there before they do for if we miss them and they go to . . . beyond? . . . what then? Will we have find two other souls to take their place? Granted, the anchors can be taken care of anytime and to myself, the souls which could be a loss is more important.
Also we do not know where all the anchors are located and much time will be spent researching to find them. Giving more time to the souls to reach their birthplace. So my vote is for the souls first, anchors second and to find the anchors as we learn of them.
