do not go mass air, sure roach cant kill voidrays, but if they kill all your shit it doesnt matter.
you need to sim city well, and land your FF well. remember this is an all in from the zerg, if you hold your third you will have a ridiculous advantage and should win the game (there are non all in varietys, a lot of them are a push while taking 4th/infestation pit) but the stephano variety (no 4th no tech just roach ling)
Its not an all in, its part of the build. You go fast max so that you have a BIGGER army, not a STRONGER army. You use this army to deal with most mid-game and early-game attacks while you tech up to Hive. You can easily recover from losing your army since your sitting on 3-4 bases.
