How do you slow down the tech of a Protoss if he has a Void ray out? That actually doesn't make any sense. Keep in mind you are on 1 base while he is on 2, even if you have a second hatchery down, you won't have any saturation.
I don't see you being able to build 2 queens by the time a void ray is out unless the protoss responds to creep at the base of his ramp with a stargate.
