Haven't dabbled much in ven/rage hybrid, but this is my spec for rage. http://www.torhead.com/skill-calc#101MMZRrRrzfRrczZf0z.2
Free force scream adds solid damage into the rotation with no cost. Enraged sunder is an absolute must. You could switch the point from dreadnought to unyielding but I find I'm not often having problems with rage with this spec. Also, strangulate isn't a great use of talents considering you have instant shockwave from enrage and force crush you typically use before that, not to mention force choke can get fully interupted even with the talent. Force choke usually gets you 3 ticks if you are getting attacked so it still does 75% bonus without the talent. Considering how much you need it to set up smashes it's not worth it. The vicious slash talents are very worthwhile when you have a lot of extra rage and smash/scream are on cooldown, or if an assassin pops his resist force cooldown.
