Firestorm has some sweet looking models have you thought about any of the other races for more variety?
Hey, well I was looking at the Aquan Prime ships to possibly use as xenos escorts, however i'm not too sure now.
I'd like to include some firepower in my fleet, so i've been looking at the Demiurg ships, however I really don't like the fact that they attempt to disengage when they are crippled, since i'll mainly be playing one off games. I don't know if it would be better to just take a few allied cruisers, and if so which cruisers should I take?
I have some Imperial and Chaos cruisers I could use, but I think I fancy using either Eldar or Tau cruisers, not sure which would be best though.
I think i'll be playing an ordnance heavy chaos fleet most of the time, so do people think I should counter it with my own ordnance in the form of Escort Carriers/Allied Cruisers or not?

I've got some firepower in the form of the RT cruiser, Murder cruiser and Stronghold.
FP9 from 3 Armed Freighters seems pretty good to me for 60pts.
I'll also have 9 attack craft squadrons, including some assault boats.
I realise that I should probably include some escorts in the list, but i'm not too sure whats best for 180pts.
Any feedback would be appreciated.
Cheers
