You don't see too much pure Blood Angels around, pretty much because most of the book is really underwhelming. Once you add in some allies they can be a great addition but pure BA is tough.
Since I'm playing in a more "casual" league (that my shooty ork list just dominated) I figured going pure BA would be the way to go. Mid-tier, not too powerful not too weak.
One of my favorite models I've ever done for my BA is my Captain with dual lightning claws. So I started with that because he's awesome.
HQ: Captain: The Angel's Wings, 2 LC, artificer armor
HQ: Sanguinary Priest: jump pack, bolt pistol, meltabombs
Troops: 10 Tactical Marines: Melta, combi-melta, heavy flamer, drop pod
Troops: 10 Tactical Marines: Plasma, combi-plasma, lascannon, Las-Plas Razorback
Elites: 10 Death Company: bolters, drop pod
Elites: 10 Sternguard: heavy flamer, 3x combi-plasma, 3x combi-melta, drop pod
Fast: 4 Bikes: combi-grav, 2x grav gun, Attack bikes with MM
Fast: 10 Assault Marines: 2x melta, Vet Sgt, power fist
Fast: 5 Assault Marines, melta, Rhino
Lots of power armor, lots of drop pod action and one assault unit. It's fun, sorta aggressive, and damn pretty if I don't say so myself.
