Urethane Wheels vs. Rubber Airless/Air Tires, Which Better for Electric Skateboarding?

In this video, I talk about why rubber wheels are preferred over urethane wheels on electric skateboards in terms of grip, safety, and high speeds. After breaking my elbow at 32mph on urethane and a few times slipping on urethane, I feel like rubber is simply way to go for faster speeds, urethane fine for smaller boards and lower speeds. What do you think?
