Basically, it sucks v_v
either you nag 1-bank because it's green (and green is the best due to K4)
that's all.
Dengar crew fires K4 from your one of YV-666 list. It works with every manuever and has the potential to play with outlaw tech. If you're using K4 instead of Dengar crew, it better be because Dengar is in another one of your ships or you have ordinance you need the locks for.
