If i remember correctly its best to stick to arbies to keep the fitting down on a bomber. The cookie cutter solo bomber setup i used to use back in wh space / 0.0 is.

Works wonders can also be fitted to the amarrian bomber but caldari and nemisis are a no go. If i remember correctly you want to use the opposite bomb to your torp damage type to do max damage. Although having the bomb bit is useless if roaming in low sec since you can't use it.
Choosing an off-racial bomb loses out on that tasty racial bonus, always use torps and bombs to match your hull type, unless in a bombing fleet in which case you need to bring the bomb type specified by your FC, ideally with the right hull to match it. Best to stick with either a bomb setup (fit meta torp launchers but your dps will be gimped) or go pure torps with 2x BCU for some decent DPS, and T2 launchers cos you get more damage out of them. A microwarpdrive will probably get you killed due to sig bloom. Painters on bombers are overrated imo cos you get a bonus on the hull to explosion velocity.
