Still debating whether to drop the captain for a priest with jump pack and use the 70 points on scout snipers. Also, unsure as to which predator variant to use, could switch to a baal for more anti-infantry??
Loving the list, and as JAMOB said the auto/las weapon loadout would probably be the best for you. You've got anti infantry in the Furioso and your own infantry's weaponry. The Priest makes your SG stick around longer and hit easier in combat, and can still be good himself (I play him with a Lightning Claw and Melta Bombs because Walkers are dicks). The auto/las adds some good transport busting power to your list so your Meltas and Fist can do what they're supposed to on heavily armoured targets.
Unfortunately Canada got rid of the penny and now my two cents rounds down to zero, so...take it for what you will.
