Well....the only Scum ship I don't own is the Hound's Tooth. I just.....am not really interested in it. Personal preference and all. I tend not to fly the big based ships much at all.
Personally, I love an Ion Scyk in a list for control. Cheap and effective.
I also love a bunch of Kihrazx Fighters for cheap damage output. Their 1 hard turn is pretty tight, as well (tight.....as in tight turn).
