Best standard WAR opener as MT?

[RhazeCain]

Hmm, an interesting topic, unlike most threads on this board.. Let's see if can keep it going. =)

How is Storm's Eye an optimal opener to Butcher's Block? What exactly are we optimizing?

"Optimal" = maximizing both enmity and damage. Measured as a total at end of "opener" sequence. Requirement during sequence that it constantly maintain more enmity than high damage opening sequences of other classes of equivalent gear level.

Sounds like people have been following that already, more or less, so I just try to articulate it a bit.

Now 2 interesting points I heard already:
A) First combo SE vs. BB: If assume that both are going to be in your opener anyway, then obviously SE->BB will be higher total enmity AND damage due to maim and SE buffing the BB combo ... IF AND ONLY IF the sequence reliably stays ahead of DPS enmity. To me, the last part is a question mark: worth it if can make it work, but I'm not sold yet.
B) Overpower vs. Tomahawk to start: A previous poster mentioned 5x and 3x enmity multipliers -- I'd like to see a source on that. Regardless though, every measurement I've seen and my own experience say that Overpower is a considerably higher enmity multiplier than Tomahawk.
The drawback of Overpower is the shorter range. Assuming Tomahawk used at max range, that means that your next weaponskill (Heavy Swing probably) comes "later" in relation to your being in melee range. Like, you Overpower, then enemy comes to you, then you wait for GCD. With Tomahawk, more or all of the GCD is spent in the enemy coming to you. So, while Overpower is clearly the higher enmity ability, the ~1 sec time difference makes the comparison result unclear in my mind.
