The Stabber is hard to fit well against other cruisers because it lacks powergrid, cpu and turret hardpoints. Outtanking or Outgunning your opponent is no option.
It is super fast and has a range bonus, so it is a good kiter. Actually it is so fast, it doesnt even need speed enhancing mods in order to kite.
The fit posted below does 300 dps at 25 km or 400 at point zero (where you don't want to be). that is from missiles, drones and turrets. it still has issues with caplife so pulse the mwd if your target is really slow. it does mostly Expolive damage. the drones are acolytes for the rare case your target has a reactive armor hardener.
