I'm unable to put the final piece into the second slot just yet (as a result of my prioritizing learning skills over engineering) but it will be the Shield Resistance Amplifiers (one of each) and I'll change it up before missions based on the enemy's damage type.

I find this fit is an excellent mission setup, allowing me to sit in one place and lob missiles at a high rate of fire into clusters of incoming enemies.  It'll be even better once I get standard missile specialization through LP and save up the money to upgrade the 'Limos' missile bays to 'Arbalest'.  A devastating hail of standard missiles is my end goal with this fit. I've got a month to work on it while I train learning skills/into my first T2 ship.  It already obliterates even the hardest L1 Missions without breaking a sweat.  I want to keep working on it and see if I can't run some L2s in it as well.
