Competitive Blood Angels in 7th Edition 40K

In light of 7th edition, I have been bouncing around ideas for a competitive Blood Angels list. Some of my initial considerations- not all encompassing:
Assault is still weak with regard to jump pack Blood Angels- they're just too expensive and lack oomph.
Psychic powers are a lot less reliable to cast this edition and require a significant amount of point investment to work.
AV 11 is still weak, but, I am interested to test fast Rhinos and Razors. I don't think they will hold up, especially as armies transition to take on high AV.
