I've been considering what to use for my 2nd spec, I'm the raid leader and most trusted tank in our guild, so I'm taking Vene's dual prot spec post to heart. Definitly staying with the standard 15/5/51 for normal duty, but for my 2nd spec instead of going dps or higher threat I'm looking at maximum survival, best cooldowns and defensive talents.

Tentatively 5/15/51, using Imp Demo Shout, Commanding Presece, Imp Spell reflect, and Imp diciplines. Glyphs of Shield Wall, Last Stand and Spell Reflect.
