I have a really big problem with Kha'ZixSquare Kha'Zix. I love to play him, and with my current play guide, I can muster a decent KDA, split push moderately well, and assassinate well. However, my problem is that while playing him, I feel like I am not getting the utility that I could from my Unseen Threat Unseen Threat.

My general method for playing is to max and evolve Taste Their Fear Taste Their Fear first, which really isn't the best idea, so as of late I have been maxing it first, but evolving Leap Leap instead.

When watching the LCS, I find that pro players like to max and evolve Void Spike Void Spike first.

My question is: What do you guys think the best option is.

I've been considering maxing my Q first, but evolving it last (evolving W-E-Q in that order). I've also been considering maxing W first, with the same evolution pattern.

Another question: Is evolving Void Assault Void Assault worth it?

Anyway, that's it for today. Thanks for taking the time to read, and all answers that I get in the comments will be helpful and much appreciated.
