Slow Weapon & Deep Wounds -- Math Challenge

Once I got a chance to look at my damage spreads, I've noticed Deep Wounds is doing substantially better than I expected. This may be, as another poster suggested, because both Damage Shield and Thunder Clap can proc it now.

Here's the challenge, if anyone wants to take on the math:

**Can a slow weapon be superior for Warrior Threat under single target situations?**

Keep in mind when doing the following that we'll have 25% crit on all cooldowns except Revenge, including subbing normal attacks for Heroic Strikes (base 5% + 5% Aura + 15% from talents). There is also the possibility of Damage Shield procs if you want to factor that in.

What makes this more complicated is that you'll have to factor in both Devastate and Heroic Strike, since Devastate favors slower weapons and Heroic Strike favors faster weapons. At this time, assume the difference to be 1.6 speed (Red Sword of Courage) vs 2.5 speed (Titansteel Bonecrusher).

Finally, feel free to factor in different talent models where the Warrior has 2% Crit from Cruelty in addition to Deep Wounds (this is harder to get, but may be worth it).

I'm already certain that a slow weapon will be better for AOE tanking in almost every case. The point here is to determine how we best utilize gear sets and multiple specs.
