Throwing higher lines with the nose down
Yes, it’s true that you need to have the proper height on your shots in order to maximize your distance but too much or too little height will really make a huge difference. You always need to concentrate on keeping your wrist in the downward locked position even when you elevate your shot and release angle, this is usually the fixes the the problem of exaggerating the nose up release.
Focus on gaining the height on your shots by choosing your line, find the release angle of the disc and match that with your arm angle during the pull through. By keeping your wrist locked downward this will allow you come over the top on your shot, pushing that nose of the disc down and flying at the preferred height driving forward.
It’s definitely going to take some practice and I wish you the best of luck with your throwing sessions in the field.
