I’ve probably spent more time flying T1 and Fleet stabbers than any other single ship.
The T1 Stabber is an autocannon ship. It doesn’t have enough PG to support a good arty fit, IMO.
The Fleet Stabber is a better choice for an arty fit. Not only does the Fleet Stabber have more PG to support an arty fit, it can fit arty turrets in all of it’s high slots and has a turret tracking bonus, which is very useful for arty turrets. The Fleet Stabber also has a 40m3 drone bay and 40 mbit bandwidth compare to 25m3 and 25 mbit on the T1 Stabber.
The T1 Stabber cannot fit AC’s to all of it’s high slots, so you either go for 4 AC’s and 2 missile launchers, or use 2 high slots for utility modules.
I’m not saying the T1 Stabber is a bad ship, but if you want to fight from range/snipe, the Fleet Stabber is better suited for that role.
I’d also suggest the T1 Caldari Moa with railguns as an alternative sniper cruiser, although the Moa is noticeably slower than a Stabber and has a larger sig radius.
If you wanted to go for a Minmatar cruiser with missiles, I’d suggest you look at the Fleet Scythe instead of the T1 Scythe. The T1 Scythe bonuses are really aimed at logistics, and it can only fit 1 missile launcher. The Fleet Scythe’s bonuses are damage dealing bonuses and it can fit 4 missile launchers.
