The problem with the highest speed discs is that they are historically understable. This is no longer an issue. The Defender is here. Fast. Stable. Neither of these descriptions will be in dispute after you unleash this scorcher. You will no longer have to put away your high speed discs when the wind begins to blow. The Defender will have your back when the course and the elements conspire to take you down.
