IMO improving the back link profile of third-party pro-sites is much effective and faster as they are already ranking on page #1 or #2.
That's exactly our issue. The client ranks 1st and 2nd but the concern is:
1. two sites that rank in the top 10 below it
2. other sites that may emerge out of the blue
