Cool, I would like to see it sometime if you ever get a chance. Myself if I put too much hyzer on a disc it will flip flat but fade at the end. But this is with a sidewinder. Maybe an under stable mid is the ticket. Do you intentional OAT it as well? I remember Feldy talking about that before to achieve certain lines.
I will intentionally OAT sometimes for shots but not for this specific shot. This shot is all about having the power to do it and choosing the right disc. I use pretty beat rocs for this shot and they go upwards of 400' on this line. Its just a slow hyper flip to flat on a low line. And usually once it hits flat or slightly anhyzer it just continues to go. Its a beautiful shot when done right, but it is tricky to do.
