The Hivecult 2.0

I've been on a pretty solid winning streak (4-0) with my current list, and have a just few changes I want to make before I think it's perfect. With all the feedback I got on the last post, I think its really starting to come together. So far this is the core of what I'm running:
That leaves me with 120 points to fill in before I'm at 1500. I have been taking x4 Aberrants (x2 Picks, x2 Hammers) to fill out the missing gap, but I'm not thrilled with their performance. They make a great body guard for the Primus, but aren't really durable enough to hold up against any dedicated fire power. I feel their points cost could be used to buy something that gets more mileage. All that said I've been considering two different ways to spend the 120 points, let me know what you think, or if there is something else I should take with the remaining points:

• Adding 5 acolytes to each of the 3 squads in the Brood Cycle. That ups each of them to 10 bodies, and makes for 40 WS 5 Str 5 rending attacks on the charge per squad.
• Adding two more squads of 5 metamorphs (x3 w/ claws, x2 w/ whips) to the Sub. Assault. Gives me two more squads of Str 6/Int 7 guys that get 2d6 on the Ambush chart.
