I have a question
What is the best follower in skyrim???

I think it totally depends on your style of character.

My top 5 followers would be:

1) Eola - One handed weapons / destruction magic / stealthy (Markarth - Hall of the Dead)
2) Vorstag - Heavy armor / one handed weapons / block (Markarth - Silver Blood Inn)
3) Illia - Destruction / restoration / conjuration / alteration (Darklight Tower - only problem is if you don't keep her as a follower, you can't, at the moment, get her back. That may just be a console glitch though)
4) Aela the Huntress - Archery / one handed weapons / sneak (Whiterun, Companions)
5) Mjoll the Lioness - Two handed weapons / heavy armor / archery / oh... and she's immortal (Riften)

If you're a mage, then 2 or 5. If you're stealthy then 1 or 4. If a warrior then, well, any of them I guess (just my opinion though, of course)

im onto my third follower,2 have been killed in battle,i have vorstag as my follower now,he's pretty tough.
