I use this spec for farming early inferno:

it has good burst damage potential while still remaining good survivability. You can stay on mobs for a long time due to invulnerability, blind and seven sided strike. Only problem is that you have to kite when everything is on CD, so you have to practice when to use them. Plus, you are extremely dependant on spirit, so gear with spirit regeneration is extremely useful, when you are out of spirit you have to kite and wait a little.
