PoE Forbidden Shako, Curse builds without Flicker Strike, Ice Bite

On ssf standard. Wondering if i should create a build around both of these or drop one. Most people I saw on ninja were only running one or the other. If I run both i am thinking about putting an aura set up in staff for lvl 7 enlighten. With both I hit dot cap rather easily, but I might struggle with defences a bit. I want this to be a bosser. So mainly wondering how i fit in more defence. Main things i can think of is purity watchers eye and progenesis. POB (Just something I threw together quickly, needs a few more things) &x200B;
