PVP affliction qestionFollow

Ok heres my armory http://www.wowarmory.com/character-sheet.xml?r=Eitrigg&n=Saiitan. I'm trying to get better gear. Now the question is about the spec, should I take demonic embrace for the extra health (even though burst damage right now is too insane to even make a difference)or should I stick with the damage increasing talents. Does anyone have a spec for affliction (preferably) that does good in pvp?

I was also wondering how demo is doing in pvp? I thought maybe meta could give us a boost against those absurd burst melee classes. Any feeback?

thanks for the help
