My specc at the moment:

I'm a big fan of Iron Will, but there's actually not THAT much mobs / bosses that stun you anymore, and in most cases if the stun resist you loose aggro anyway (Skeletons in Karazhan for example, they run off if you resist their Ice Tomb)
And the reason why I chose booming voice instead of something else is because when you'r tanking, you usually don't have time to look at your buffbar, and those 2 minutes go down way too fast so another minute might save your life if you forget to refresh your shout.
