Out of the remaining players we have to consider that there are three pure spirits left. The seer, slayer and priest. The vampires I think will want to avoid them at all cost as they really need people they can convert. The only roles we know for sure are:
Wiz - Vampire (hopefully Dracula otherwise there are three vampires right now)
Dag - Seer - Pure spirit can't be converted only killed.
Noods - Innocent - Possible target for conversion just the sole reason of why would i invest two nights in a row.

So between the remaining players there is at least 1 vampire (possibly but unlikely two), the priest, the slayer and 2 (hopefully not 1) townies. I think that it would be "safe" for the priest not to protect me tonight because even though I can investigate I don't think that the vampires just want to kill someone when their numbers would be down to 1 if the town takes out wiz. If the priest leaves me off the list that means that there is a 1 in 6 chance they will protect the right person tonight. It also means that there is a 2 in 6 chance that the vampires will hit another pure soul either the priest or the slayer.
That being said I think the slayer should stake FF. He would be the nearly perfect cover for the vampire team:
1. He has stated numerous times that he wouldn't be around much due to limited computer access.
2. The evils have been going against him, while some may think that this would cause town to be less suspicious of him I can see the vampires using reverse psychology in that regard.
3. Throughout this game his play as been erratic so it would be extremely hard to detect a change in game style for him going from innocent to vamp.
4. Even if FF is innocent, which I really hope he isn't anymore, his limited computer time does not really help the town out that much.
