Voidstrike Force Staff any good?

I got this earlier and not sure if I should use it over my inferno staff. At first I thought it was the one where you make the circle on the floor and it explodes, but it's actually one where you do a big voidball thing and lob it. I tested it in the Psykhanium and it did hardly any damage to, for example, a Crusher.

Just wondering if it's worth using or scrapping for cash? Also included shots of my inferno and electrokinetic staff. Which one is best to use at level 30 and just stepping into Aurics? Cheers
