I, like so many others, have Lydia. She's doing a good job being a tank, but just isn't a particularly effective sneak. I'm also concerned about bounties if I do anything untwoard in front of her, so I've been leaving her out of a lot. So what do you think is the best sort of follower to have for this playstyle? A tank who can give you away, a squishy mage, another sneak?
