Scum list critiques?

By Grand Moff Terra, in X-Wing Squad Lists

Now that I have the lancer I figured I'd make a list with it. Tried a couple out, enjoyed flying it with the firespray, but kath's ability didn't come up enough to convince me it was worth it, so I decided that what with the tractor beam shenanigans I can pull with ketsu and title, emon with bombs would be fun. So here you go:

Push and Pull (100)

Ketsu Onyo (49)
Push the limit
Gyroscopic targeting
k4 security droid
Shadowcaster

Emon Azzameen (51)
Ion pulse missiles
Tractor beam
seismic charges
Andrasta
scavenger crane
thermal detonators
conner net

Basically trying to put people where I want them then drop bombs on them. Any Ideas on improving it? Would like to keep the lancer, but the firespray is optional
