Starting off the build with Whirlwind (Hurricane) to keep enemies flying towards you as it makes maintenance of a high fury level easier.
Battle Rage (Ferocity) is just a slight boost to movement speed so you could alter to Bloodshed, for more AoE, if your areadamage is high.
You can't have a barb speed build without Sprint (Marathon). A flat 40% speedboost is extremely welcome to make you go even faster, but consumes a lot of fury if spammed.
That's why I'm running with War Cry (Charge!) most of the time. I opt away from a deffensive rune on War Cry simply because the extra +50 fury can save the build from running out at times. You might go for Veteran's Warning or Impunity as a more traditional choice, if you are taking big hits. With Chilanik's Chain in the cube you gain a 40% speedboost for 10 sec after using War Cry.
Ignore Pain (Bravado) is both used deffensively and as a n extra speed boost. Ignore Pain is baseline a 50% damage reduction and with Bravado a +40% movement speed booster. As the classic build I run with Pride of Cassius simply because the increase in duration of Ignore Pain results in a longer movement speed boost!
Last but not least Wrath of the Berserker (Insanity). At this point in D3 this skill is obligatory for an barb almost. Insanity is just the standard +50% dmg boost.
