Taking hooks late game does not have very many advantages... If you think about it a reactor hook would be pointless because by now you should have a tech of 4 a supply hook would be pointless because you should have two bases and with two bases more HSP...   other than that the only hook left getting that would be valuable late game would be the mega turret....only my opinion
