Super Class never caught on as a regular competitive format intended for shorter, outdated courses that couldn't be lengthened. Players in general would still rather use their regular hi-tech discs on short courses, including many of the veteran players who cut their teeth on lids because they don't have to throw the newer discs as hard. And it suffered from being limited in the disc varieties needed to successfully compete. The Zephyr is king with the Te Moko and Hero 235 (Innova) being close in the running. Just get maybe two weights of one of those discs and you're set.
The UltraStar is Super Class and we hoped it might encourage more crossover from the Ultimate crowd. However, it doesn't go as far and is wider than the Zephyr. Their Junior Ulty disc (Sky Pro) maybe could compete with the Zephyr but I don't believe Discraft ever made it in the heavier Super Class weights to find out.
