The Switch disc made by MVP Disc Sports was PDGA Approved as of 2-10-2014.
"The Switch is a slightly understable fairway driver that will work as a neutral compliment to the Servo. It is part of a new class of fairway drivers with a lower power requirement and more controllable speed. Its extended GYRO™ Push and understable profile offers smooth controlled turnovers and a delayed minimal fade. This disc will excel with it's ability to cruise for low power throwers. The controlled turnover in conjunction with the with minimal fade will allow for superb accuracy in tight fairways. The Switch is set to release on February 21." - by MVP Disc Sports
