Double Swing Barbarian advices needed


Diabloii.Net Member
Hi everyone, good day to you all.

This is using only DS and maxed synergy of Bash. I really don't like the speed boost of Frenzy (very hard to control and i miss a lot so get hit so much) and will have no point on that. Using 2x Baranar's Star and i want to try Stone Crusher and Schaefer's Hammer on switch.

1. Stone Crusher for %40 CB and +30 STR. (1 socket available, so advices here too)
Schaefer's Hammer for %20 IAS and chance to cast Static Field. (1 socket available, so advices here too)
Which one should be the main weapon to get best of this combination?
2. As this build will be mostly the SP build; should i max Iron Skin or Shout for highest defense? Or should i raise both?
3. Defiance merc or Blessed Aim merc?

Any help much appreciated, thanks.
