[G][H] Bronze zerg solution to skytoss?

I know its a new season, and the ladder matchups will settle down, but I'm getting crushed by skytoss. I am a "top ten" bronze zerg, have been for a couple of seasons. Even though I watch a lot of Day9 and am trying to be a better gamer.

Even when I have fully upgraded corruptors and hydra and lots of static spines, in late game, skytoss is crushing me. Upgraded and charged void rays just melt my corruptors and hydras.
Is there some unit that will kill them?Or do I just need to be more aggressive and win the game before it gets to skytoss?
