Hi! Need opinions on which is better:

1) Robo Ashwood Bow (with 3x Shaels + 2x 20/15 jewels) = 60 IAS, that would give me options like Bloodfists and crafted 10IAS/Knockback gloves for the 63 IAS breakpoint (and thus could use String of Ears as belt for %DR)

2) Robo Ashwood Bow (with 2x Shaels + 3x 20/15 jewels) = 40 IAS, that would force me to use Death Sash + Gloves for the 63 IAS Breakpoint or Twitchthroe armor. In this case I would get Cannot Be Frozen but no Knockback

3) Robo Ashwood Bow (with 2x Shaels + 2x 20/15 jewels + Nef) 40 IAS, that would force me to use Death Sash + Gloves or Twitchthroe for the 63 IAS Breakpoint. In this case I get less damage but Cannot Be Frozen + Knockback

So the main question is:
Knockback and Cannot be Frozen are VERY necessary for LLD? Which would you consider better?

Option 1
You will have the option to use anything based on matchups. You may want Death Sash CBF or String of Ears MDR and DR. You have the option to use KB gloves, Rare Gloves, or Bloodfists.

Option 1 is best

Best in slot rare is 2pnm 10ias with good adds.like dex resist mana etc

Kb is rlly only needed vs barbs
