That looks pretty decent, I'd probably stick with one primary just because you can get so much more utility or damage out of other skills. Cleave w/ rupture + ground stomp w/ wrenching smash is a great aoe combo, even better with vengeance.

I use either this or a variation of this build: http://us.battle.net/d3/en/calculato...Vik!abg!cZYcaa

I managed to solo kill SK and the butcher on inferno last night with 5 stacks of NV using this build, so it's great for elites and handles fairly well against bosses.

Unfortunately as a barb you'll have to spec as tank for hell+ due to the high damage output of mobs and close proximity required to engage. Barbs don't really have many effective kiting tools that I know of. This means your dps will be poor, most likely lower than any other class. With buffs in combat I sit around 14k but I'm really only geared for act 1. Also in a group you'll want to completely forget about damage and focus on stuns and tanking (stomp, leap, ignore pain, war cry, threatening shout etc.)

My general strategy is just to engage in chokes and avoid being surrounded, using seismic slam to knock back anything close to me. Ground stomp is a good fury generator and stun for when enemies are charging/casting their big abilities.

So far I'm getting annihilated by act 2 mobs, 2-shot even by trash (white) monsters. I'll try some different combinations and report back with my success.
