PoE JolteonSQ builds

I'd like to put together a Cold Conversion Sweep character. Seen a few Sweep videos online (FastAF & Mathil) but want to do the gearing my own way. 1. putting Sweep in a pseudo 7/8 link helm similar to this one in the picture 2. 6 link totem setup in weapon (voidforge or crafted rare using Fleshripper/ Banishing Blade/ Exquisite Blade) 3. double curse setup in chest (Explode or Carcass Jack depending on ascendancy) or just get curses on rings and use this 6L for another setup What would be the ideal ascendancy to go with? Trying to decide between Assassin, Slayer, Berserker, or Raider.
