looking for best build for speed/dmg

any ideas or links would be great. im used to saders so im trying something new,

thanks all!

Don't get any better than Danettas + Natalya for T6 speed rifts.

My build: http://us.battle.net/d3/en/profile/AngryLink-1921/hero/63264272

I started my build off these guys:
http://www.diablofans.com/builds/53623-2-2-0-armageddon-natalyas-t6-gr45
http://www.diablofans.com/builds/3299-speedrifting-desolacers-armageddon-dh-build

But ultimately, I ended up differing from them a bit. With the fast paced movement, I'm not fond of stopping to aim the crashing rain belt so I opted for omryns chain which also helps to proc bane of the trapped-cull of the weak passive more easily. Roll through enemies for strongarm procs. Also works nicely if you use a certain program to make it so holding down your vault (right click) will hold down the RoV for automatic casting. Just make sure to turn off the voice sounds or you'll constantly hear "Can't do that yet." I can carry 4 man rifts myself and could still use a better mainhand/higher lvl gems and you only really die if you vault into an explosion or a field of arcane sentries.
