Hi - maybe I can get things started ...
You have a challenging reception environment. You have few close, powerful stations and those are widely separated. The closest major market appears to be Greenville, at compass 90.
How much do you want to spend? If this were for me, I would buy an Antennas Direct DB8e, put it on the roof and point one panel to the north and one panel to the east. Your antenna site should be in clear air, as high as you can reasonably put it, and not obstructed to the horizon by trees or buildings. Then, I would connect the antenna to a single TV, move the antenna around (side to side and up and down, if practical) and change the aim of the panels until I got the best mix of channels. You should get 36, 21, 45, 16 and possibly 24 with this setup. Then, if you want more channels, add a VHF high antenna like the Antennacraft Y5713 or Y10713 on the same mast, and point it at the VHF high station you want most, ie 9, 7, 13, 14. Connect the two antennas with a UVSJ or preamp. Joining antennas like this has been discussed a lot in other posts, like here:

W05AO is an analog repeater of WLOS 13. If I really wanted WLOS, in your situation I would point right at it with a dedicated VHF-high antenna, and ignore the repeater.
The alternative is to get a large directional UHF-VHF high antenna like the Antennacraft HBU-55 and point it at Greenville (compass 90). You could also mount this antenna on a rotator and change the orientation remotely to get different stations. Your TV must allow adding stations manually, aside from the automatic scan.
hth!
