The thing when TOPing autos is that the window of opportunity is very narrow. it must be done removing the 5th or 6th node, why? because once the 5th pair of leaves fully opens, then flowering will begin and once that happens you cannot TOP. Also keep in mind that every time you TOP you will increase the time the plant take to finish by 1 week. I would either LST or TOP once and then LST.
