Okie dokie. Lets start shall we?
First things first: don't take the Sanguinor, take Mephiston. Period.
Next, don't waste points on tacticals. If you want tacticals, play Ultramarines or Fists. We take Assault marines to kick ass and scouts to be cheap.
Pump up and pimp up your death company. If they're going in the Redeemer, take 10 guys plus a terminator Rec/Libby/Chappy. Take all pistols since you won't be shooting and take some power axes for those pesky 2+ saves.
Don't take Sanguinary guard unless you're taking Dante. They suck as Elites. They suck slightly less as troops
Your "dreadknought" (its not a baby carrier, it doesn't have the silent K) should be have a Twin Linked Auto Cannon on each arm for some budget light at/aa or it should be a Furioso in a pod with a Heavy Flamer and Frag Cannon for lots of Template goodness. Also you have at least 5
DC so you can make it a
DC dreadnought with Blood Talons for maximum blending capability. Just be sure to either give it a pod or a magna grapple to catch those pesky tanks.
Predators are hit and miss. They're not bad in the
BA codex just remember to keep the autocannon turret and either take Heavy Bolters to shoot infantry or Lascannon sponsons for a quick moving tank hunter (you can move 12" fire both lascannons and snapshot the autocannon due to it being a fast vehicle)
If you have the codex, great! Be sure to read it a few more times. If not, buy the codex, read it a few hundred times. Don't be afraid to post total unit costs next to the unit when you post a list as if one of us spots a discrepancy we can check it and give you those points back

because everyone needs more dakka.
And as always it's a good idea to put the army name and points level you're shooting for in the title. Cheers and happy wargaming!
