I am looking to farm players 8 chaos FAST

I know other characters may clear faster, I am aware of this. Barbarian is my favorite and I need to level one for PVP so I want to run chaos with one until then.

I have a 5os phase blade and I will make a grief, but which offhand is best for clearing chaos the fastest? Ebotdz? Doom? I have no idea and need help.

Also if there are other gear choices that will help in this please let me know

For chaos are you looking to go Berserk? If so, you don't really need the off-hand weapon and could go Stormshield

Some basic gear options off the top of my head

Hlords
Guillaumes or Arreats
LoH gloves
Ravenfrost
Dungos
Goreriders
Dual spirit switch

Im looking to go what has the fastest clear speed

Probably berserk to clear uniques fast. Frenzy is fun but less so in CS.
