My take away.What was summary of these vids (can't watch currently)? As a total newb to this, a couple months ago I researched and concluded that for those of us on the site who want to buy this just for shits and giggles the best plates are the ceramic ones from RMAdefense.com $135 gets you a level IV ceramic, which is lighter than the steel, and has a much longer pedigree (ceramic plates--not this specific one), NIJ certified, is Level IV. I have some doubt about the effectiveness of anti-spalling on the steel armor.
