I am a bit confused. If old site is radioactive with "large unhealthy backlink history", why would you want to associate your new clean site with that radioactive history?
The old brand established our market online over 10 years ago. We have customers that refer to thisdomain as our product catalog (even though our new domain (brand) has the catalog. For branding and our customers, it makes sense to close the domain out and 301 redirect it over to our current brand domain.
In essence, business-wise this is what we should do.
