As I read through this thread, I realize how handicapped you are if you avoid the wiki and the spoilers here. Had I known about the Steed Stone, I likely would have went heavy armor. In fact, even if I had wanted light, I could have avoided wasting a perk to make my armor weight nothing. I would have known how to get Black Soul credit with Azura's Star. Etc and so on. Oh well, I think I can win this thing in grand fashion anyways, and I'll know I did it (mostly) on my own. But it definitely makes it tougher than it needed to be.
