What the best armor rune word for Whirlwind barbarians?

Im wonder what armor to use for pvm endgame for whirwind barbarians. Currenly im wear full Disciple set with Arreat face helm, not bad as cheap budget build but i dont like the relative good amulet from the set and definitly hate the boots. Now Diablo droped me one Highlord wrath amulet and fund Lo rune too.
Now i can make Fortitude and equip Highlord with Gore Rider boots.
Second options that i trade one Ber and make Chains of Honor.
What i dont know which is better?
The 300% ED from the Fortitude or the 2 allskills and higher resistancia from the Chains of Honor.
I read somewhere that barbarians dont need that many allskills from gear but more enchanced damage.
I played so far lightsorc and hammerdin and these only needed the bonus skills.
So this is my first physical damage character after two caster type.
Thanks for the help.

Fortitude is around 25% too 33% of your damage for ww

Thanks for the answer and for the links, i will read them.

For faster runs and killing I prefer Enigma with Reapers toll on a merc. You can just tele on top of your target(s) then Reapers toll procs Decrepify almost instantly.
