I think I will to be honest

I've always loved Shrikes. This will have to be my Eternal War list, for Maelstrom I think I'll replace the Rippers and Shrikes with three units of 15 Hormagaunts - gotta love that speed

Shall probably leave the heavy lifting to the big bugs in that regard
Thought 1: I'm going to test
1) Two Boneswords, one Rending Claws, three Toxin Sacs.
2) Remove the Malanthrope and have four Shrikes, two with WhipSwords, two with Claws, four Toxin Sacs, four Flesh Hooks, four Adrenal Glands.
3) Remove the Malanthrope and have four Shrikes, three with WhipSwords, one with Claws, four Toxin Sacs, four Flesh Hooks.
4) Remove the Malanthrope and have five shrikes, two with WhipSwords, five Toxin Sacs, five Flesh Hooks.
I think number one is going to be the best option (even though I would have liked to put Flesh Hooks on) as the Malanthrope can babysit those Carnifexes, but we shall see, I do have a large amount of Synapse (two Flyrants, two Warriors, 1 Shrike) and units that function reasonably well outside (Rippers, Exocrine). Shall certainly have to test each one
Thought 2: Actually those 15 size Hormagaunt Troops seem pretty viable...have them bubble wrap the Carnifexes and Living Artillery and stop them getting tarpitted...Flyrants flying about causing nuisance...so many options..
