Sure-Grip Nova

I used to own a skate shop that sponsored some elite speed skaters and tried many different plates. You may spend more money but, the Nova plates, if properly set up and with the right wheels will be as fast as any of the expensive metal plates as they are a close relative of the Ultimate III. They are light and yet very strong with triple structural cross bracing inside the jump bar. They are also very stable at high speed but remain responsive at lower speeds. I don't know about derby applications but for speed skating they get 5-stars. Definitely recommend it.
