Problem 1, bow ties are highly directional and do best when aimed directly at the transmitter tower(s).
Your 2 main directions to receive signals are almost 90 degrees apart, which means you will need to split your aiming directions to try and pick up stations from both directions. A 4 bay will do better in that regard as their beam width is a bit wider than an 8 bay.
Problem 2, is the trees, they will block a significant amount of signal. Having said that if you can get your antenna up high enough you may find a sweet spot where the signal is getting over the trees. Sometimes a few feet one way or the other can find a spot where the signal is getting though. (Look up multi-path interference.)
Problem 3, 4 TV's. You have some close strong signals and some not so strong, also affected by trees. You will be cutting the signal to each TV to 1/4 of what the antenna picks up and you have long cable runs which drops even more signal.
That indicates that a pre-amp might be needed, BUT, with close strong stations you can easily overload your tuners with it causing even more loss of stations.
I think if you start with a 4 bay, mounted as high as you can get it, run to one TV with the shortest run, no splitter and see what you can get. Aim it about 260 degrees magnetic which is 20 degrees to the south. This should still pick up your stations from 285 but give you a chance at the really strong channels at 185 degrees mag.
