I like more 'things' and did not know that black holes were not gravity behemoths so it makes sense to fluff it so that a hither unknown effect of a black hole is to exert a massive pull on materials that are constructed from TN minerals.
This then opens up a tech tree that would negate the effects of a black hole in the same way that more armor on a ship negates the drag of a nebula.
You could use shields as a way to block that 'pull' from a black hole but have it such that each level of black hole reduces the shield level by a certain amount (over time maybe, like taking damage?).
So, if you want to traverse a black hole then you have to heavily shield your ship and run the risk that they fail before you get to your destination.
