I think that almost everyone can agree that light armor is best for an archer. I was using a full set of Dragonscale armor, until I found did the Thalmor Embassy MQ. After escaping, you pop out near the edge of the map. I saw a stone marker, and went over to it. After killing my horse by falling off of a small drop, I found the steed stone. This stone increases your carry weight by 20 and makes
armor give you no movement penalty. This means that you'll be able to wear heavy armor as an archer, and still be able to move around quickly. While you are wearing it, you can let your heavy armor skill go up to 70 until you can get the perk that makes heavy armor weigh nothing. Now, during this time, you'll be sacrificing some sneak because of the noise, but the ebony mail chestpiece can make you much better at sneaking.
I love comments! The good, the bad, and the ugly!
