Get rid of Buffalo mk 2, it's just bad. Hammerhead and Falcon should have their missiles upgraded to non-single versions (or changed to sabots or reapers or whatever you feel like). Falcon's rear energy turrets (and maybe front turrets too) can be switched to PD, you won't be fighting with your back turned anyway. And you should replace mining blasters with any other medium energy weapon.
In general it's fine and I'm surprised you have troubles dealing with pirates. Are you doing bounties, or are just getting jumped on by some random pirates?
