Who is the best rogue in the zerg at the moment? pvp wise

[lite]

I have a plan for a pvp challenge where I destroy a Velious BIS rogue while rockin Kunark junk. Thinking in Kurn's tower, still coming up with the rules.(open to suggestions)

40k if they can defeat me, event will be streamed.

I promise not to give you the Eddard sig treatment.
