The Resistor by MVP Disc Sports was PDGA Approved as of 9-23-2013.
"The Resistor is part of a new slower family of fairway drivers with a more controllable speed and diverse range of weights. The combination of its flat overstable profile and GYRO™ technology allows it to resist turn and experience a strong reliable fade. This disc executes accuracy and rangeability like a dream." - by MVP Disc Sports
