Welcome to Gaia! ::

So now that I've become considerably comfortable with my muta-ling build (though not entirely finished with it yet)

I'm considering to begin practice for my secondary build (though not full out ladder play) on a new build involving roach/hydra and nydus worms perhaps with a splash of infestors, which will be my way of dealing with an early aggression in which I cannot get muta ling to work, and simply to change things up once in a while.

The problem being I simply don't have enough practice with roach hydra builds and timings, if anyone happens to know some really good replays that demonstrate this kind of build (or close to it) please let me know, also any information to can provide would be great.

You should find madfrogs replays as far as I've seen his great with roaches.

As a Protoss player (not much help to a Zerg player XP) I usually go for three builds:

1) Double Warpgate build with a Forge to create a good defense and leading me to a Cybernetics Core for Warpgate Tech.

2) Forge --> Warpgate --> Cyber --> Stargates

3) Cannon Rush biggrin
