SakashiroFor the main mod I'll go with lightweight. I've already replaced the A-rated interdictor with a D-rated one. This way I'll keep the ship's maximum speed even with all three hardpoints occupied.
Oh, do you plan to PvE with that exact build with minimum shielding and no HRP and MRP whatsoever?
Frag canons have quite limited effective range - you will be close and personal with your enemies. Some of them will even have fighters.
Please call me when you try so. I would like to have a sit on the first row for this.
