What Innova says: The Toro is a flat-top, overstable mid-range—co-designed by Calvin Heimburg—made for powerful sidearms and windy conditions. It is an overstable, beadless mid-range that can handle a lot of torque. Perfect for powerful sidearms and windy conditions.
 
"Calvin Heimburg was the inspiration behind the Toro. He wanted a flat-top, overstable, mid-range disc that he could have confidence in—something that could handle his level of forehand torque. After several variations, the Toro was created and named by Calvin."
