We are having a 1000pt Veterans Tournament at my FLGS and I am considering running an IG list.

HQ - CCS w/ ML and Astropath 95pt

Troop - Vet squad with 3 meltaguns and 9 shotguns 100pt

Elite - Marbo 65pt

Fast - Vendetta 130pt

Heavy - Medusa 135pt
Heavy - Medusa 135pt

Fortification - Bastion w/ Icarus LC 110pt

The CCS starts in the Bastion and holds up other flyers with the Astropath while shooting the ML and ILC at targets of opportunity, since the CC and squad all have the same BS he can give orders to both the ML and ILC. The veterans ride inside the Vendettas, the Medusas start on either side of the Bastion and rain down templates while Marbo will come in on the backside of my opponents deployment to throw his template and hopefully tie up a unit before dying. I am looking for the meanest 1000pt list so any suggestions will definitely be taken under advisement. I have a HUGE IG army so I can switch out pretty much any thing in this list.
