I was lucky and got an expired PR6 domain (ok I also invested some good money). It was a non commercial website with several strong links from gov sites and also a wikipedia link. I built a nice looking PBN but now I am wondering if it might be an overkill if I link to my money site from a PR6 site and might look suspicious. Of course I link to other high authority domains as well. But just from inner pages. On the homepage I intended to just place a link to my money site to get the full fire going. Would that be ok or should I be more cautious? My moneysite is 2 years old, PR1, has some good links but nothing like that so far.
