Unfortunately for bomb users, scum really doesn't have any good bombers. Not to say it doesn't have good ships with bombs. Fire sprays and aggressors can carry bombs, but only as a secondary. Slave 1 only carries 2, Andrasta three, and stock sprays and aggressors can only carry one each. Also sprays and aggressors are far better at other things. Forget them.
The bomb load out Y-wing can carry two bombs (with munitions) and while is good at other things, is built with ordinance in mind. So prox mines work well with this build, but I like the spread of cluster mines better. I feel they are worth the extra 2 points. Back burner the bombers for a minute.
The Scyk interceptor has to be the coolest little ship in the game. More specifically the heavy Scyk at 16 points. I'm not even going to touch on the explodey fun here because for just a point more you can put a tractor beam on this puppy and never have to deal with the enemy being in position again, so long as you roll well.
Three of these and two of those
Cartel spacer with title and tractor beam - 17 x 3
Syndicate thug with bomb load out, extra munitions and cluster mines - 24 x 2
If you want a little more use from your y's and don't mind losing the spread of the cluster mines, equip prox mines and auto blaster turrets. Go btl a4 or not, it's free. Also 99 points, so yay initiative bid.
