Here is what Innova says about the Toro:
 
At [4|2|0|4] the Toro is a flat, overstable, beadless mid-range that can handle the type of torque that world class disc golfers produce. Calvin Heimburg provided Innova founder and president Dave Dunipace with substantial input to help create this extra-reliable, slow-speed midrange to his specifications, with added attention to the in-hand feel of the disc.
