I just went back to a dungeon that I fled from a Dragon Priest in earlier in my game. Lol. I've since leveld up and acquired a few new goodies. I brought Lydia along, and I almost never use Followers.

I decked her out with:

Steel Plate Helmet
Heavy Chitin Armor
Heavy Chitin Gauntlets
Heavy Chitin Boots
Ebony Sword (Superior)
Ebony Shield
Amulet of Stendarr
Ring of Minor Blocking

I haven't really Smithed or Enchanted anything crazy yet. Still leveling smithing.

I just wanted an idea of who and what people use in terms of Followers. I'd like to make use of them more often and on other characters.

Oh, and we just wrecked the Dragon Priest and his 4 Draugr Wights.

I Keep Cicero with default armor, Highest dagger available, Sanguine Rose and I give him any staffs I happen to find on my travels. He uses them all and makes an army when I give him many summoning staves.
