So many options! It really depends upon what you'd like to do with those huge multi-cannons.
For PvE, many choose to
overcharge them and apply the
corrosive shell experimental effect. It's a powerful combination. If you're looking for another application (anti-Xeno?), something else will be better.
You might also get some good ideas on the
Ships & Engineers forum. It's more focused on this kind of thing, so I'd expect more thorough, well-reasoned answers. They will, however undoubtedly ask what you're hoping to do if you don't state it at the beginning of a query.
