With a 750 pt army in the Dark Angels, usually I wouldnt use a total Ravenwing or Deathwing unless I had a good list of them against the right army. Here is some ideas or tips to help you out with your 750 pts of DA
Chaplains are usually a good choice of low point space marine armies and Dark Angels are a perfect example. This low of points you maybe could pull off Sammael.
Usually scouts are a popular pick b/c of long range cheap infantry. Personally I dont like scouts, but its not like its a bad pick by any means. Dreadnoughts are another good choice for anti-tank/heavy.
Troops would be your general combat squad space marines with weapon upgrades. The usual pick for Dark Angels weapon upgrades are Plasma Guns/Cannons (depending on squad size) and/or Meltaguns. Another good pick personally I believe is a Missile Launcher. Vet Sgt with power weapon isn't a bad idea either, but usually a last point filling add in to make sure you get all your other needs first.
The only fast attack I would use is the Ravenwing Land Speeder with HB/AC takes up 100pts but is a very good anti-horde. If your HQ choice is already Sammael on Land Speeder in a 750pt army, don't use any fast attack b/c of the high cost of most of the DA selection.
Not a huge need, but if you can fit some in, do it. Usually just one lone predator with Lascannons and Heavy Bolters (130 pts). Maybe even a Vindicator with dozer blade (130 pts) which can really draw some fire to keep your other units alive and lay down some heavy damage.
I have just now made 2 versions of 750 pt DA army lists if you would like to see them. PM me if you want to and ill PM back the 2.
