In your case, I'd suggest pointing the antenna toward the NE to start with. If you wish, you can take the time to perform a full sweep of the horizon or use your TVFR to determine the aim point to see if an alternate aim point can still provide reliable reception of the main group of signals while adding one or more off angle options.
Given that many TV tuners require the use of an automated scan function to program the real > virtual channel map, and offer no means to manually add real > virtual entries,a rotator often forces the user to perform a full channel scan each time the antenna aim is adjusted (very time consuming and frustrating). Also, when there are two or more TVs connected, only one viewer can control the antenna aim leading to one or more unsatisfied viewers. So generally I avoid the use of a rotator.
If you find that the antenna must be aimed to the NE in order to provide reliable reception of those signals, and you are missing one or more signals from other directions, I'd suggest a separate axillary antenna, separately cabled to a stand alone tuner.
