Fyi, I believe I have fixed my airball issue without using any type of protector/shield. Took two small pieces of weather stripping, and stuck them to the back of the targets at the very top. Now, when the target is hit, it stays angled down, and does not launch the ball. Played seven games, and really tried to hammer both targets. Not one ball came off the playfield. I think this is similar to an idea that was posted earlier in this thread, but I did not remove the stock padding. YMMV.
