Throw barb recommendations

I've been thinking about trying a throw barb, so my Zerker has an entire stash filled with throwable weapons that may or may not be junk. I've got

Lacerator,

Deathbit, and a bunch of rares with %ED, Life steal, IAS, attack rating, some replenishes quantity, and increased stack size. Are there specific things that I should look for on a throw barb weapon beyond that? Any tips?

I do have a

Razortail and was going to make a Wisdom.

GG-rare throwing weapons not withstanding, ethereal

Lacerator and ethereal

Warshrike are BiS weapons for throw-barbs.

The

Deathbit in the offhand paired with a fast rare, magic or

Blood Weapon will carry you through nightmare until you can wear the

Lacerator at level 68 in your main hand. As a

Helm I would suggest GFace.

Belt is optional imo. When you have a

Warshrike in the offhand you have enough piercing percentage.

The fastest IAS breakpoint I believe is only possible with an act 1 merc with Faith bow.

Currently I am playing a throw-Barb ladder hardcore. Since it is hardcore I do not prioritize max damage and I only play solo. He is at level 84 and I am very happy with him. Here is the my set-up at maxroll: https://maxroll.gg/d2/d2planner/id1qr060
