dude, your goal should be to only make turrets when you need them. you should recognize it's not optimal and try to use them when they're necessary
if you're going to try and master a build, you should try and master a good one and not a ****ty one that won't work often when you move up.
in other news, i played one of the weirdest zvt games i've ever played earlier today going on no sleep around noon. it all started when i wasn't paying attention and accidentally went pool first for no good reason.
counter to hellions more lings imo.
