So be careful not to play in too narrow or too crowded places because the Frisbee is really going very far and we just easily go astray, see it can hurt people.
It also has a certain fragility, because composed of a flexible portion surrounding a rigid plastic, the rigid plastic (visible violet part of the photo) that maintains the shape of the Frisbee, if this part breaks, the flexible part can not maintain the aerodynamics frisbee.
That's why the sprint model is more robust because more compact.
In summary, if you want to throw your frisbee over very long distances on lawns or beaches cleared, the aerobic pro is for you; if you have less space and your style is more aggressive prefer him aerobic stronger sprint.
