Lightning Strike Jugg

Thinking about making a Lightning Strike Jugg for Flashback. Planning on stacking accuracy and think I have the gear worked out but having issues deciding on auras and links.

2 Ahn's Might
Obscurantis
Hyrri's Truth
Oskram
Pacifism
Rest rares

For heralds and auras I have no clue. Obviously Precision but that's kind of awkward since it takes a set amount of mana and I won't have a lot.

For main links I'm thinking of the below but unsure on the final slot. Maybe Lightning Pen or Damage on Full Life. I'll try to PoB it but it's hard to get a good feeling in regards to the melee portion vs the projectile.

Lightning Strike
Phys to Lightning
Ancestral Call
Elemental Damage with Attacks
Multistrike

For single target help I guess it's a toss up between Vaal Ancestral Warchief and Vaal Double Strike. Not sure which is better, assume VDS would benefit from auras and the totems wouldn't? Being able to cast a totem without souls would be nice though.

Thanks in advance for any suggestions.
