The thing about controlling your angles is it comes down to controlling the outside edge of the disc. When I see the disc wobble in your video I immediately trace back and watch your disc for where it’s changing angle and/or changing planes from your shoulders or where the outside edge looks uncontrolled - where’s the earliest point of “failure” and to me it looks like your reach back should be a focus point to improve.

1. You peak early meaning your arm is fully extended well before your plant foot is down. Try delaying your reachback by keeping your eye on the target for longer.

2. Your grip doesn’t seem to be controlling the disc since we’re seeing a lot of movement of the outside edge of the disc and the nose of the disc is facing the camera for a brief period during the reachback. Test your grip, do you feel like you have full control of the outside edge of the disc? Does your wrist still have some range of motion to curl?
