I`ve updated the unofficial compatibility list, thanks for the input!
Despite you have no policy "from the top", I would start from your needs.
What and how often would you like to copy to tapes? For how long? etc.
As for general recommendations, there is no recommendations paper to read so far besides the user guide. But I would search forums for tape best practices
for more info. You can also just ask us here.
Btw, you might be interested in new tape features
in upcoming v9 release.
