EC combat patrol, needs help

6 Noise Marines (4 with sonic blasters, 1 with blastmaster, 1 Asp. Champ. with sonic blaster)
=155

6 Daemonettes
=90

=388

The other option is exhanging the ACs' sonic blasters for power weapons, which adds some more choppy and takes it up to 398 points. But whichever choice I make, what should I spend the spare points on?

I don't like it.

You have two squads, that while can level a respectable amount of shots, die just as easily as a basic trooper 10 points cheaper than them.

The Daemonettes, while good in theory, aren't a good addition here. You have two squads that you want to desperately keep out of Close Combat. If you get close enough to effectively summon the daemonettes, you stand a good chance of being counter charged.

Lastly, you have no "bite." Rending is okay, but with only six daemonettes, they can't hold their own in a fist fight.

Here's what I suggest - drop the Sonic Blasters all together. Make two units of Close Combat squads. Maybe give them Infiltrate, if you feel necessary. Give a Powerweapon and Daemonic Strength to the champions. Maybe Mutation if you happen to have extra points left over.
