To bring this discussion back to machine guns and answer an older question, TAKE THE DUAL MG. It offers much more firepower, and the higher and wider spread bullet density makes it damn hard to NOT hit missiles and fighters. Also, the double OP cost is TOTALLY worth it, because the flux costs are negligible, so you can spend your other OP elsewhere, and save weapon slots.
This being said, my favorite PD is ten wings of Talons and ten wings of Piranas
. I end up starting my battles with a swarm of Talons (usually ten wings), two of my fastest carriers (usually
Concords Condors, because I increased their speed and cost in the csv file, to make them not useless), and a swarm of Piranas (I send them out until I run out of them, even if it means waiting for more points to be captured).
Have you ever tried to fire missiles through a wall of swarmers, bombs, and vulcan cannons? And did it end with the missiles getting through?NOTE: My favorite PD in terms of guns is the Light Dual MG, in case you didn't infer that from the first paragraph.
EDIT: Condors, not Concords
