Plates are changing as time goes on. They all started off at a basic angle, same material, etc. Today however, everything is completely different. There are different angles, different materials, different styles, different trucks, different cushions, and so much more. Becoming popular are the 16 degree and 45 degree kingpin angled plates. The rise in popularity is because they help the skate's turn radius, and the stability of skaters while on the track. The materials went from an original tool steel plate, which was very heavy, to aluminum, aircraft aluminum, and now in some places carbon fiber plates. They started with weights of a few pounds, and went to less than one pound put together. Take a look and see what kind of plate may suit you the best.
