Need help picking boss killing skill for zerker (no cloaked in savagery)

Hey guys,

So struggling here on deciding what boss killing skill I should run on my berzerker. The catch is I will NOT have Cloaked in Savagery. I will be trash clearing w/ Abberaths Hooves so having a secondary attack for single target is a must. I will be going hidden potential, will have both duration clusters, EZ access to EO, EE, and relatively easy access to VP and any of the nodes in that area.

I was thinking maybe Scorching Ray or Scorching Ray + CWC + Firestorm might be good ideas. Not sure if BV would be smart when I wont be having Cloaked in Savagery. Any other skills that may be better options?

Thank you for the feedback :)
