Let me just say that Joe Delago and his people at Werksan USA are outstanding individuals. They had a sale of their old style training plates, which I snapped up because I was covetting those things. Anyhoo, something went amiss with the shipment of the 10KG plates. They quickly fixed it by sending out the new style of training plate. Their service is excellent so if you need some bumpers and have the cash give them a try.
