Which staffs will be used by followers, when given to them?

This is an interesting question. Because of this question, I started giving Lydia all sorts of staffs that I found in my current game. She is using paralysis staff with great enthusiasm on top of the conjuration staffs and destruction staffs, so we will add that to our list. I took away chain lightening staff from her because it's an Area of Effect spell staff and it damages me all the time when she uses it. I gave her a healing staff, but she hasn't used it, yet. I'll give her a fear staff when I find one.

[Edit] I made the test more complete by giving Lydia a whole bunch of staffs I do not remember her using before and going through a couple of caves and bandit camps.
