Sugestions for Flasks

Hello There Everyone !

I'm Plaing Flame Totem Blood Magic Chieftain and i have some questions about flasks that I could use / Should use

Currently my flasks are:
I Use Topaz flasks because i have 3% of Lightning Resist at the moment :P

I think they're preaty decent But Im wondering if I Should get

- Atziri's Promise
- Rumi's Concoction
- The Wise Oak
and / Or
- Kiara's Determination

What do You think ? I'll add that i have a bit of trouble with Chaos resistance (At the moment -60% On merciles, You can check my gear in my profile)

If you have any sugestions please let me know :D

Well, first off, you need to cap your lightning resistance. With gear. Don't worry about chaos resistance. Plenty of people play with -60%. If you get some on gear here and there later on, as an afterthought, that's nice.
