With a 14 in main hatch you are set up nicely to also go for Overlord speed and Overlord dropships very quickly after lair. It is more risky, but you can add that option in if you see the T open themselves to it. (which is good for doom drops and even 1OL fake-scout baneling drops) It transitions well into expanding on islands and defending tank drops and reapers on cliffs like on lost templer (which is impossible to FE on safely imo)
