One thing to keep in mind and I don't know if it matter on TZ but the spotlights can really glare of the LCD. I have an LCD in my AC/DC and I used spacers so the top of the screen is leaning back slightly. That glass really reflects the spot lights and playfield lights. I don't think it would matter on metal back box Sterns as they are already leaned back a little. The LED doesn't have this issue at all.
