Erm throw from flat ground
You could get your elbow farther forward before chopping open. If you need to throw overstable discs anny for s-curves for D in calm weather you might benefit from less stable discs. This video was obviously shot in the wind but even then knowledge of the disc can be used to get it farther than harder fading discs. Provided speed and glide are at least equal. You can pull a little closer to the body too.
Flat shots need running on the center line of the tee and planting each step on the center line. Anhyzer needs running from rear right to front left with the plant step hitting the ground to the left of the line you're running on. Hyzer is the mirror of that.
