I don't even attempt bang backs as they definitely look like they could harm the machine. However, I do death saves all the time on the local Tee'd Off machine, and I usually at least attempt them on most modern sterns I've played. (AC/DC and LOTR seem to be pretty easy to death save on)

Do death saves carry the potential to damage the machine? On location pinball in this area is pretty rare and I certainly don't want to break anything. I typically put a leg under the machine to help lift the front legs and move left then back right to bump the ball up to the right flipper. Only asking because someone in the thread mentioned the potential for damage.
