I tend to run them on most of my ships, I have 5-10 normal launchers and a decent magazine, then something like 50-100 box launchers, this allows for more flexibility I find, I can launch small salvos for the times I need those, and I can do a really huge one for when I need to bust shields or depopulate a planet or something. Or even mid sized ones that can scale as needed to test enemy point defense or something.
