If you are not satisfied with the dummy plates available in the market, why not try these ESAPI Non-Ballistic Training Plates from Team Wendy... "Now that you have the ability to obtain the training plates, you can put your Ballistic Plates aside for the times that you do need them. The TW Training Plates weight in at 5lbs each and measure 8.75 inches x 11.75 inches and they can be easily inserted into your carrier (for us, it is our HSGI Weesatch).  They are a colored in a bright blue, and this is to ensure that you cannot grab these in case you need to use your Ballistic Plates.  The plates are made from a Polyurethane material that makes them virtually break proof."
