I find raiders tend to be good at either hit and runs or shooting, but rarely both. depending on starting ship points and what expansions you have it is possible to truly crank out some good specialist ships. assuming that everyone and there brother pays the points for "planet bound for a millennia" it is more than possible to start off with 3 arciotech items.( I did this with random rolls on the warrant path)
so for my hit and run cobra I have the modified drive, teleportarium, bridge of antiquity and murder servitors. if my math is correct I get a + 50 to do hit and runs. this also happens to be the ship we put torpedoes on, more for that initial long range punch before closing in. the dorsal mars macrocannons are more place holders at this point until they can be refitted. all for around 48 SP
on the other hand our long range meritech shrike ends up with a +20 to BS score due to the ship(=5)martial hubris(=5)auto stabilized auguar array(+5) and auto-targeting matrix(+5)
it is equipped with a sunhammer lance and good turbo shard cannon. we also got planet bound for this one. 51 SP starting.
used in a pair they are quite deadly.
