Wow. Amazing amount of data and insight. Thank you for taking the time to research and present this and share your personal choices. I have just a few questions. In terms of ceramic/plastic, do you have any concerns about:1. High temperature exposure? Kinda rules out leaving it in the car in the summer, yeah?2. Low shelf life/warranty? If you bought a $400 plate are you going to scrap it after it “expires” in 5 years? If not, how long are you comfortable keeping/using it?3. Hairline cracks/damage? I’ve heard it is recommended to x-ray ceramic plates at least once a year or once every other year for hairline cracks that are not visible to the naked eye as these cracks could compromise the plate’s effectiveness. On top of that, the type of x-ray machine, how to x-ray, what to look for, and what type of cracks/damage constitutes a compromised plate are things ordinary people don’t understand and even those who claim they do know, they have various sometimes conflicting opinions themselves…. Thank you, John!
