Sword / Shield. Much more versatile, so you can switch out one for a hand of magic without having to completely holster/re-equip your two hander. Plus I like to just Captain America everything. It would be pretty cool if the shield were throwable.
I think if you want to go two handed, in my opinion, you have to use either Elemental Fury Shout or The Longhammer, because otherwise they are too slow.
