I ran Dual Wield for the longest time, but to keep that sustainable in late Inferno you need a lot of attack speed/Life on Hit that I just didn't have, so I sword and shield now.
Not sure if you have all of these but the three best for where you are at, for me, were:
Seize
Resolve
Transcendence
Transcendence is literally broken until late game. You almost cannot die.
