I'm not sure. The best setup for reception would be a separate antenna and preamp for each direction, but you probably wouldn't want to do that because it would be very inconvenient with 3 TVs; it would need switches and rescanning.
I can suggest some tests you can make to see if it is even possible to get good reception from 73 and 122 degrees true. Try aiming both panels at 83 degrees magnetic and see what you get from Toronto. Then try aiming both panels SE at 132 degrees magnetic to see if the escarpment is no longer a problem.
If you then get good reception from both of those problem directions, you will need to decide which channels are most important to you and how much trouble and expense you are willing to do.
Possible solutions:
1. Just one direction, and be happy with that.
2. One antenna and a rotator. That would mean rescanning when you change directions unless your TVs can add a channel after scan like a Sony, and all 3 TVs would be required to receive only that direction. Also, you wouldn't want to repair the rotator in January, and you wouldn't like to wait for the rotator to change direction.
3. Two directions with 2 antennas aimed directly at the transmitters. That would need an A/B switch for each TV, and you would need to rescan unless the TV can add a channel after scan.
4. Two or three antennas. Antenna A would go to the antenna input of the TV and antenna B and C would go to separate tuners with their output going to the aux input of the TV.
5. Two or three antennas combined into one coax with custom combiners from Tin Lee Electronics (expensive) or from Jan Jenca (much less expensive).

Max local and US channels if possible

Not too much chance for US channels; maybe WNLO+WNYB and WNED PBS on a very good day.
