OK How about removing the overhead screen, altogether. Then, the
only surfaces that the ball would have to hit would be below the
red on all three walls. If a home run ball hits above the red
on the rear wall - it's out. If it manages to make contact - even
on a "blooper" - it's good.
You might need to call a contractor or two to "raise the
roof a couple hundred feet or so....but no big deal!!!
